commit 01eed86d50af9fab27d876fd677b86259ebe9de3 upstream.

There might be devices out in the wild where the board name is GMxXGxx
instead of GMxXGxX.

Adding both to be on the safe side.

Input: i8042 - add TUXEDO Stellaris 15 Slim Gen6 AMD to i8042 quirk table 2024-10-04T14:38:32+00:00 Werner Sembach wse@tuxedocomputers.com 2024-09-10T09:40:08+00:00 7220b935bc978ace6047404f1ad2c6beb6fdf0eb commit 3870e2850b56306d1d1e435c5a1ccbccd7c59291 upstream. The Gen6 devices have the same problem and the same Solution as the Gen5 ones. Some TongFang 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.
