[PATCH AUTOSEL 6.6 03/39] Input: atkbd - skip ATKBD_CMD_GETID in translated mode

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 936e4d49ecbc8c404790504386e1422b599dec39 ]

There have been multiple reports of keyboard issues on recent laptop models
which can be worked around by setting i8042.dumbkbd, with the downside
being this breaks the capslock LED.

It seems that these issues are caused by recent laptops getting confused by
ATKBD_CMD_GETID. Rather then adding and endless growing list of quirks for
this, just skip ATKBD_CMD_GETID alltogether on laptops in translated mode.

The main goal of sending ATKBD_CMD_GETID is to skip binding to ps/2
mice/touchpads and those are never used in translated mode.

Examples of laptop models which benefit from skipping ATKBD_CMD_GETID:

* "HP Laptop 15s-fq2xxx", "HP laptop 15s-fq4xxx" and "HP Laptop 15-dy2xxx"
  models the kbd stops working for the first 2 - 5 minutes after boot
  (waiting for EC watchdog reset?)

* On "HP Spectre x360 13-aw2xxx" atkbd fails to probe the keyboard

* At least 9 different Lenovo models have issues with ATKBD_CMD_GETID, see:
  https://github.com/yescallop/atkbd-nogetid

This has been tested on:

1. A MSI B550M PRO-VDH WIFI desktop, where the i8042 controller is not
   in translated mode when no keyboard is plugged in and with a ps/2 kbd
   a "AT Translated Set 2 keyboard" /dev/input/event# node shows up

2. A Lenovo ThinkPad X1 Yoga gen 8 (always has a translated set 2 keyboard)

[PATCH AUTOSEL 6.6 04/39] Input: i8042 - add nomux quirk for Acer P459-G2-M

From: Esther Shimanovich <eshimanovich@chromium.org>

[ Upstream commit 335fe00319e030d481a54d5e0e68d50c5e672c0e ]

After the laptop lid is opened, and the device resumes from S3 deep
sleep, if the user presses a keyboard key while the screen is still black,
the mouse and keyboard become unusable.

Enabling this quirk prevents this behavior from occurring.

[PATCH AUTOSEL 6.6 05/39] Input: amimouse - convert to platform remove callback returning void

[Sasha Levin]

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

[ Upstream commit 42b8ff47720258d1f6a4412e780a480c139773a0 ]

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

[PATCH AUTOSEL 6.6 28/39] HID: nintendo: Prevent divide-by-zero on code

From: "Guilherme G. Piccoli" <gpiccoli@igalia.com>

[ Upstream commit 6eb04ca8c52e3f8c8ea7102ade81d642eee87f4a ]

It was reported [0] that adding a generic joycon to the system caused
a kernel crash on Steam Deck, with the below panic spew:

divide error: 0000 [#1] PREEMPT SMP NOPTI
[...]
Hardware name: Valve Jupiter/Jupiter, BIOS F7A0119 10/24/2023
RIP: 0010:nintendo_hid_event+0x340/0xcc1 [hid_nintendo]

 hid_input_report+0x143/0x160
 hidp_session_run+0x1ce/0x700 [hidp]

Since it's a divide-by-0 error, by tracking the code for potential
denominator issues, we've spotted 2 places in which this could happen;
so let's guard against the possibility and log in the kernel if the
condition happens. This is specially useful since some data that
fills some denominators are read from the joycon HW in some cases,
increasing the potential for flaws.
