de391d1250 Input: fix typo in keycode validation supporting large scancodes
Check the input_keymap_entry keycode size (u32) instead of the device's
(void*) when validating that keycode value can be stored in the keymap.

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=22722

6f07d31e46 Input: aiptek - tighten up permissions on sysfs attributes
Sysfs attributes affecting device behavior should not be, by default,
world-writeable. If distributions want to allow console users access
these attributes they need to employ udev and friends to adjust
permissions as needed.

5fdbe44d03 Input: do not pass injected events back to the originating handler
Sometimes input handlers (as opposed to input devices) have a need to
inject (or re-inject) events back into input core. For example sysrq
filter may want to inject previously suppressed Alt-SysRq so that user
can take a screen print. In this case we do not want to pass such events
back to the same same handler that injected them to avoid loops.

17d01f28e1 Input: pcf8574_keypad - fix error handling in pcf8574_kp_probe
It is not allowed to call input_free_device() after calling
input_unregister_device() because input devices are refcounted and
unregister will free the device if we were holding he last referenc.

The preferred style in input/ is to make input_register_device() the
last function in the probe which can fail.  That way we don't need to
call input_unregister_device().

Also do not need to call input_set_drvdata() as nothing in the driver
uses the data.

8c5188b6d3 Input: atkbd - add 'terminal' parameter for IBM Terminal keyboards
Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate
using a protocol similar, but not identical to the AT keyboard protocol.
(Models known to be like this include 6110344, 6110668, 1390876, 1386887, and
possibly others.)

When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they
can be connected to a standard PC, with three caveats:

a) They can only use scancode set 3; requests to use anything else are
quietly ignored.
b) The AT Command to request Make, Break and Repeat codes is not properly
interpreted.
c) The top function keys on a 122 key keyboard, and the arrow/edit keys in
the middle of the board send non-standard scancodes.

C) is easily taken care of in userspace, by use of setkeycodes
B) can be taken care of by a userspace hack (that makes the kernel complain
in dmesg)
A) is fixable in theory, but on the keyboard i tested on (6110668), it seems
to be detected unoverridably as Set 2, causing userspace oddities that make
it harder to fix C).

Enclosed is a small patch to the kernel that fixes A) and B) in the kernel,
making it much easier to fix C) in userspace. It adds a single kernel
command line parameter that overrides the detection that sets these boards
as set 2, and instead of sending the Make-break-repeat command to the
keyboard, it sends the make-break command, which is properly recognized by
these keyboards. Software level key repeating seems to make up for the lack
of hardware repeat codes perfectly.

Without manually setting the command line parameter (tentatively named
atkbd.terminal), this code has no effect, and the driver works exactly as
before.

73b14484fb Input: i8042 - add Sony VAIOs to MUX blacklist
The Sony VPCZ1 doesn't support active multiplexing and trying to enable
it causes keyboard to stop working. Since most (all?) VAIOs do not have
external PS/2 ports nor they implement active multiplexing properly, and
trying to enable MUX usually messes up keyboard/touchpad, let's simply
disable MUX probing based on board name (VAIO).

b50b521694 Input: export input_reset_device() for use in KGDB
KGDB, much like the resume process, needs to be able to mark all keys that
were pressed at the time we dropped into the debuggers as "released", since
it is unlikely that the keys stay pressed for the entire duration of the
debug session.

Also we need to make sure that input_reset_device() and input_dev_suspend()
only attempt to change state of currenlt opened devices since closed devices
may not be ready to accept IO requests.

b584efc9ea Input: ad7879 - prevent invalid finger data reports
Considering following scenario - the touch is present on the screen
at the beginning of the last conversion sequence, but by the time
the last sequence is finished, the finger is lift off. The AD7879 data
available interrupt signals (DAV) completion, however some X,Y values
are not valid because the screen inputs were floating during the
acquisition.

The AD7877 acts differently here, since it only asserts DAV if the
touch is still present when the conversion sequence finished.

Based on the fact that this can only happen in the last sample of the
repeated conversion sequence, we simply skip the last (short glitches
are filtered by the AD7879 internal median and average filters).
This doesn't cause noticeable side effects, since the minimum conversion
interval is 9.44ms. We receive ~100 waypoint samples per second, so we
simply delay the result by 9.44ms.

We also reject samples where pressure is greater than pressure_max.

d537155a09 Input: adp5588-keys - use more obvious i2c_device_id name string
KBUILD_MODNAME normalizes "-" to "_".  This is non-obvious and results in
the id name for ADP5588 being "adp5588_keys" while the other supported id
is "adp5587-keys".  So avoid this define and use an explicit string as the
id name.

This fixes a regression introduced by the dynamic allocation of absinfo

According to the AD7877 datasheet:

Each transfer operation is 16-bit. If multiple read/write operations are
to be performed, CS must be taken high after the end of each read/write
operation before another read/write operation can be performed by
taking CS low again.

Make sure CS toggles after each transfer in the message.
