Subject: Input: i8042 - add Fujitsu Lifebook E5411 to i8042 quirk table
From: Szilard Fabian <szfabian@xxxxxxxxxxxxx>
commit 80f39e1c27ba9e5a1ea7e68e21c569c9d8e46062 upstream.
In the initial boot stage the integrated keyboard of Fujitsu Lifebook E5411
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.
i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:308A) not working at all.
Since the integrated touchpad is managed by the i2c_designware input
driver in the Linux kernel and you can't find a PS/2 mouse port on the
computer I think it's safe to not use the PS/2 mouse port at all.
