Input: i8042 - skip selftest on ASUS laptops
On suspend/resume cycle, selftest is executed to reset i8042 controller. But when this is done in Asus devices, subsequent calls to detect/init functions to elantech driver fails. Skipping selftest fixes this problem. An easier step to reproduce this problem is adding i8042.reset=1 as a kernel parameter. On Asus laptops, it'll make the system to start with the touchpad already stuck, since psmouse_probe forcibly calls the selftest function. This patch was inspired by John Hiesey's change[1], but, since this problem affects a lot of models of Asus, let's avoid running selftests on them. All models affected by this problem: A455LD K401LB K501LB K501LX R409L V502LX X302LA X450LCP X450LD X455LAB X455LDB X455LF Z450LA [1]: https://marc.info/?l=linux-input&m=144312209020616&w=2 Fixes: "ETPS/2 Elantech Touchpad dies after resume from suspend" (https://bugzilla.kernel.org/show_bug.cgi?id=107971) Signed-off-by: Marcos Paulo de Souza <marcos.souza.org@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
