[ Upstream commit e7c4ebe2f9cd68588eb24ba4ed122e696e2d5272 ]
Use the general touchscreen method to config the max pressure for
touch tsc2046(data sheet suggest 8 bit pressure), otherwise, for
ABS_PRESSURE, when config the same max and min value, weston will
meet the following issue,
[17:19:39.183] event1 - ADS7846 Touchscreen: is tagged by udev as: Touchscreen
[17:19:39.183] event1 - ADS7846 Touchscreen: kernel bug: device has min == max on ABS_PRESSURE
[17:19:39.183] event1 - ADS7846 Touchscreen: was rejected
[17:19:39.183] event1 - not using input device '/dev/input/event1'
This will then cause the APP weston-touch-calibrator can't list touch devices.
root@imx6ul7d:~# weston-touch-calibrator

No devices listed.
And accroding to binding Doc, "ti,x-max", "ti,y-max", "ti,pressure-max"
belong to the deprecated properties, so remove them. Also for "ti,x-min",
"ti,y-min", "ti,x-plate-ohms", the value set in dts equal to the default
value in driver, so are redundant, also remove here.

[ Upstream commit 2a2565272a3628e45d61625e36ef17af7af4e3de ]
On a MSI S270 with Fedora 37 x86_64 / systemd-251.4 the module does not
properly autoload.
This is likely caused by issues with how systemd-udevd handles the single
quote char (') which is part of the sys_vendor / chassis_vendor strings
on this laptop. As a workaround remove the single quote char + everything
behind it from the sys_vendor + chassis_vendor matches. This fixes
the module not autoloading.

[ Upstream commit 94dc3471d1b2b58b3728558d0e3f264e9ce6ff59 ]
The strlen() function returns a size_t which is an unsigned int on 32-bit
arches and an unsigned long on 64-bit arches. But in the drm_copy_field()
function, the strlen() return value is assigned to an 'int len' variable.
Later, the len variable is passed as copy_from_user() third argument that
is an unsigned long parameter as well.
In theory, this can lead to an integer overflow via type conversion. Since
the assignment happens to a signed int lvalue instead of a size_t lvalue.
In practice though, that's unlikely since the values copied are set by DRM
drivers and not controlled by userspace. But using a size_t for len is the
correct thing to do anyways.

[ Upstream commit 2d2cb3066f2c90cd8ca540b36ba7a55e7f2406e0 ]
syzbot is reporting cancel_delayed_work() without INIT_DELAYED_WORK() at
l2cap_chan_del() [1], for CONF_NOT_COMPLETE flag (which meant to prevent
l2cap_chan_del() from calling cancel_delayed_work()) is cleared by timer
which fires before l2cap_chan_del() is called by closing file descriptor
created by socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_L2CAP).
l2cap_bredr_sig_cmd(L2CAP_CONF_REQ) and l2cap_bredr_sig_cmd(L2CAP_CONF_RSP)
are calling l2cap_ertm_init(chan), and they call l2cap_chan_ready() (which
clears CONF_NOT_COMPLETE flag) only when l2cap_ertm_init(chan) succeeded.
l2cap_sock_init() does not call l2cap_ertm_init(chan), and it instead sets
CONF_NOT_COMPLETE flag by calling l2cap_chan_set_defaults(). However, when
connect() is requested, "command 0x0409 tx timeout" happens after 2 seconds
from connect() request, and CONF_NOT_COMPLETE flag is cleared after 4
seconds from connect() request, for l2cap_conn_start() from
l2cap_info_timeout() callback scheduled by
schedule_delayed_work(&conn->info_timer, L2CAP_INFO_TIMEOUT);
in l2cap_connect() is calling l2cap_chan_ready().
Fix this problem by initializing delayed works used by L2CAP_MODE_ERTM
mode as soon as l2cap_chan_create() allocates a channel, like I did in
commit be8597239379f0f5 ("Bluetooth: initialize skb_queue_head at
l2cap_chan_create()").

Since commit edc6afc54968 ("tty: switch to ktermios and new framework")
termios speed is no longer stored only in c_cflag member but also in new
additional c_ispeed and c_ospeed members. If BOTHER flag is set in c_cflag
then termios speed is stored only in these new members.
Since commit 027b57170bf8 ("serial: core: Fix initializing and restoring
termios speed") termios speed is available also in struct console.
So properly restore also c_ispeed and c_ospeed members after suspend to fix
restoring termios speed which is not represented by Bnnn constant.

Currently the gsmi driver registers a panic notifier as well as
reboot and die notifiers. The callbacks registered are called in
atomic and very limited context - for instance, panic disables
preemption and local IRQs, also all secondary CPUs (not executing
the panic path) are shutdown.
With that said, taking a spinlock in this scenario is a dangerous
invitation for lockup scenarios. So, fix that by checking if the
spinlock is free to acquire in the panic notifier callback - if not,
bail-out and avoid a potential hang.

ACS-5 section
7.13.6.36 Word 78: Serial ATA features supported
states that:
If word 76 is not 0000h or FFFFh, word 78 reports the features supported
by the device. If this word is not supported, the word shall be cleared
to zero.
(This text also exists in really old ACS standards, e.g. ACS-3.)
The problem with ata_id_has_dipm() is that the while it performs a
check against 0 and 0xffff, it performs the check against
ATA_ID_FEATURE_SUPP (word 78), the same word where the feature bit
is stored.
Fix this by performing the check against ATA_ID_SATA_CAPABILITY
(word 76), like required by the spec. The feature bit check itself
is of course still performed against ATA_ID_FEATURE_SUPP (word 78).
Additionally, move the macro to the other ATA_ID_FEATURE_SUPP macros
(which already have this check), thus making it more likely that the
next ATA_ID_FEATURE_SUPP macro that is added will include this check.

dyndbg's control-parser: ddebug_parse_query(), requires that search
terms: module, func, file, lineno, are used only once in a query; a
thing cannot be named both foo and bar.
The cited commit added an overriding module modname, taken from the
module loader, which is authoritative. So it set query.module 1st,
which disallowed its use in the query-string.
But now, its useful to allow a module-load to enable classes across a
whole (or part of) a subsystem at once.
# enable (dynamic-debug in) drm only
modprobe drm dyndbg="class DRM_UT_CORE +p"
# get drm_helper too
modprobe drm dyndbg="class DRM_UT_CORE module drm* +p"
# get everything that knows DRM_UT_CORE
modprobe drm dyndbg="class DRM_UT_CORE module * +p"
# also for boot-args:
drm.dyndbg="class DRM_UT_CORE module * +p"
So convert the override into a default, by filling it only when/after
the query-string omitted the module.
NB: the query class FOO handling is forthcoming.

stub-fn is too permissive:

[ 42.933220] dyndbg param is supported only in CONFIG_DYNAMIC_DEBUG builds

This caused no ill effects, because unknown parameters are either
ignored by default with an "unknown parameter" warning, or ignored
because dyndbg allows its no-effect use on non-dyndbg builds.
But since the code has an explicit feedback message, it should be
issued accurately. Fix with strcmp for exact param-name match.
