[ 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)

[ 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.
