commit feee70f4568650cf44c573488798ffc0a2faeea3 upstream.
While doing my research to improve the xpad device names I noticed
that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013,
so that Razer Sabertooth instance looked wrong and very suspect to
me. I didn't see any mention in the official drivers, either.
After doing more research, it turns out that the xpad list
is used by many other projects (like Steam) as-is [1], this
issue was reported [2] and Valve/Sam Lantinga fixed it [3]:
[1]: dcc5eef0e2/src/joystick/controller_type.h (L251)
[2]: https://steamcommunity.com/app/353380/discussions/0/1743392486228754770/
[3]: https://hg.libsdl.org/SDL/rev/29809f6f0271
(With multiple Internet users reporting similar issues, not linked here)
After not being able to find the correct VID/PID combination anywhere
on the Internet and not receiving any reply from Razer support I did
some additional detective work, it seems like it presents itself as
"Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00.
Leaving us with this:
* Razer Sabertooth (1689:fe00)
* Razer Sabertooth Elite (24c6:5d04)
* Razer DeathAdder 2013 (1532:0037) [note: not a gamepad]
So, to sum things up; remove this conflicting/duplicate entry:
{ 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 },
As the real/correct one is already present there, even if
the Internet as a whole insists on presenting it as the
Razer Sabertooth Elite, which (by all accounts) is not:
{ 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 },

commit 754ff5060daf5a1cf4474eff9b4edeb6c17ef7ab upstream.
The AlpsPS/2 code previously relied on the assumption that `char` is a
signed type, which was true on x86 platforms (the only place where this
driver is used) before kernel 6.2. However, on 6.2 and later, this
assumption is broken due to the introduction of -funsigned-char as a new
global compiler flag.
Fix this by explicitly specifying the signedness of `char` when sign
extending the values received from the device.

A lot of modern Clevo barebones have touchpad and/or keyboard issues after
suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them
have an external PS/2 port so this can safely be set for all of them.
I'm not entirely sure if every device listed really needs all four quirks,
but after testing and production use. No negative effects could be
observed when setting all four.
The list is quite massive as neither the TUXEDO nor the Clevo dmi strings
have been very consistent historically. I tried to keep the list as short
as possible without risking on missing an affected device.
This is revision 3. The Clevo N150CU barebone is still removed as it might
have problems with the fix and needs further investigations. The
SchenkerTechnologiesGmbH System-/Board-Vendor string variations are
added. This is now based in the quirk table refactor. This now also
includes the additional noaux flag for the NS7xMU.

Merge i8042 quirk tables to reduce code duplication for devices that need
more than one quirk. Before every quirk had its own table with devices
needing that quirk. If a new quirk needed to be added a new table had to
be created. When a device needed multiple quirks, it appeared in multiple
tables. Now only one table called i8042_dmi_quirk_table exists. In it every
device has one entry and required quirks are coded in the .driver_data
field of the struct dmi_system_id used by this table. Multiple quirks for
one device can be applied by bitwise-or of the new SERIO_QUIRK_* defines.
Also align quirkable options with command line parameters and make vendor
wide quirks per device overwriteable on a per device basis. The first match
is honored while following matches are ignored. So when a vendor wide quirk
is defined in the table, a device can inserted before and therefore
ignoring the vendor wide define.

As can be seen in elants_i2c_power_off(), we want the reset GPIO
asserted when power is off. The reset GPIO is active low so we need
the reset line logic low when power is off to avoid leakage.
We have a problem, though, at probe time. At probe time we haven't
powered the regulators on yet but we have:
devm_gpiod_get(&client->dev, "reset", GPIOD_OUT_LOW);
While that _looks_ right, it turns out that it's not. The
GPIOD_OUT_LOW doesn't mean to init the GPIO to low. It means init the
GPIO to "not asserted". Since this is an active low GPIO that inits it
to be high.
Let's fix this to properly init the GPIO. Now after both probe and
power off the state of the GPIO is consistent (it's "asserted" or
level low).
Once we fix this, we can see that at power on time we no longer to
assert the reset GPIO as the first thing. The reset GPIO is _always_
asserted before powering on. Let's fix powering on to account for
this.

The touchpad present in the Dell Precision 7550 and 7750 laptops
reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However,
the device is not a clickpad, it is a touchpad with physical buttons.
In order to fix this issue, a quirk for the device was introduced in
libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:
[Precision 7x50 Touchpad]
MatchBus=i2c
MatchUdevType=touchpad
MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50*
AttrInputPropDisable=INPUT_PROP_BUTTONPAD
However, because of the change introduced in 37ef4c19b4 ("Input: clear
BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped
anymore breaking the device right click button and making impossible to
workaround it in user space.
In order to avoid breakage on other present or future devices, revert
the patch causing the issue.

Before these changes elan_suspend() would only disable the regulator
when device_may_wakeup() returns false; whereas elan_resume() would
unconditionally enable it, leading to an enable count imbalance when
device_may_wakeup() returns true.
This triggers the "WARN_ON(regulator->enable_count)" in regulator_put()
when the elan_i2c driver gets unbound, this happens e.g. with the
hot-plugable dock with Elan I2C touchpad for the Asus TF103C 2-in-1.
Fix this by making the regulator_enable() call also be conditional
on device_may_wakeup() returning false.

though the device is a buttonpad and therefore does not have those
buttons.
This behavior has forced userspace applications like libinput to
implement different workarounds and quirks to detect buttonpads and
offer to the user the right set of features and configuration options.
For more information:
https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/726
In order to avoid this issue clear the BTN_RIGHT and BTN_MIDDLE key
bits when the input device is register if the INPUT_PROP_BUTTONPAD
property bit is set.
Notice that this change will not affect udev because it does not check
for buttons. See systemd/src/udev/udev-builtin-input_id.c.

commit bc7ec91718c49d938849697cfad98fcd9877cc26 upstream.
The spaceball.c module was not properly parsing the movement reports
coming from the device. The code read axis data as signed 16-bit
little-endian values starting at offset 2.
In fact, axis data in Spaceball movement reports are signed 16-bit
big-endian values starting at offset 3. This was determined first by
visually inspecting the data packets, and later verified by consulting:

Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.
This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.
So this patch moves dev->work initialization before registering input

[ Upstream commit 9222ba68c3f4065f6364b99cc641b6b019ef2d42 ]
We've got a bug report about the non-working keyboard on ASUS ZenBook
UX425UA. It seems that the PS/2 device isn't ready immediately at
boot but takes some seconds to get ready. Until now, the only
workaround is to defer the probe, but it's available only when the
driver is a module. However, many distros, including openSUSE as in
the original report, build the PS/2 input drivers into kernel, hence
it won't work easily.
This patch adds the support for the deferred probe for i8042 stuff as
a workaround of the problem above. When the deferred probe mode is
enabled and the device couldn't be probed, it'll be repeated with the
standard deferred probe mechanism.
The deferred probe mode is enabled either via the new option
i8042.probe_defer or via the quirk table entry. As of this patch, the
quirk table contains only ASUS ZenBook UX425UA.
The deferred probe part is based on Fabio's initial work.

commit a02dcde595f7cbd240ccd64de96034ad91cffc40 upstream.
A new warning in clang points out a few places in this driver where a
bitwise OR is being used with boolean types:
drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical]
data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This use of a bitwise OR is intentional, as bitwise operations do not
short circuit, which allows all the calls to touchscreen_get_prop_u32()
to happen so that the last parameter is initialized while coalescing the
results of the calls to make a decision after they are all evaluated.
To make this clearer to the compiler, use the '|=' operator to assign
the result of each touchscreen_get_prop_u32() call to data_present,
which keeps the meaning of the code the same but makes it obvious that
every one of these calls is expected to happen.

commit f8f84af5da9ee04ef1d271528656dac42a090d00 upstream.
Even though we validate user-provided inputs we then traverse past
validated data when applying the new map. The issue was originally
discovered by Murray McAllister with this simple POC (if the following
is executed by an unprivileged user it will instantly panic the system):
int main(void) {
int fd, ret;
unsigned int buffer[10000];
fd = open("/dev/input/js0", O_RDONLY);
if (fd == -1)
printf("Error opening file\n");
ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer);
printf("%d\n", ret);
}
The solution is to traverse internal buffer which is guaranteed to only
contain valid date when constructing the map.

[ Upstream commit e479187748a8f151a85116a7091c599b121fdea5 ]
Some buggy BIOS-es bring up the touchscreen-controller in a stuck
state where it blocks the I2C bus. Specifically this happens on
the Jumper EZpad 7 tablet model.
After much poking at this problem I have found that the following steps
are necessary to unstuck the chip / bus:
1. Turn off the Silead chip.
2. Try to do an I2C transfer with the chip, this will fail in response to
which the I2C-bus-driver will call: i2c_recover_bus() which will unstuck
the I2C-bus. Note the unstuck-ing of the I2C bus only works if we first
drop the chip of the bus by turning it off.
3. Turn the chip back on.
On the x86/ACPI systems were this problem is seen, step 1. and 3. require
making ACPI calls and dealing with ACPI Power Resources. This commit adds
a workaround which runtime-suspends the chip to turn it off, leaving it up
to the ACPI subsystem to deal with all the ACPI specific details.
There is no good way to detect this bug, so the workaround gets activated
by a new "silead,stuck-controller-bug" boolean device-property. Since this
is only used on x86/ACPI, this will be set by model specific device-props
set by drivers/platform/x86/touchscreen_dmi.c. Therefor this new
device-property is not documented in the DT-bindings.
Dmesg will contain the following messages on systems where the workaround
is activated:

Despite these errors, the elants_i2c driver stays bound to the device
(it returns 0 from its probe method despite the errors), blocking the
i2c-hid driver from binding.
Manually unbinding the elants_i2c driver and binding the i2c-hid driver
makes the touchscreen work.
Check if the ACPI-fwnode for the touchscreen contains one of the i2c-hid
compatiblity-id strings and if it has the I2C-HID spec's DSM to get the
HID descriptor address, If it has both then make elants_i2c not bind,
so that the i2c-hid driver can bind.
This assumes that non of the (older) elan touchscreens which actually
need the elants_i2c driver falsely advertise an i2c-hid compatiblity-id
+ DSM in their ACPI-fwnodes. If some of them actually do have this
false advertising, then this change may lead to regressions.
While at it also drop the unnecessary DEVICE_NAME prefixing of the
"I2C check functionality error", dev_err already outputs the driver-name.
