From: Dennis Wassenberg Date: Thu, 8 Mar 2018 23:32:09 +0000 (-0800) Subject: Input: i8042 - add Lenovo ThinkPad L460 to i8042 reset list X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b56af54ac78c54a519d82813836f305d7f76ef27;p=linux.git Input: i8042 - add Lenovo ThinkPad L460 to i8042 reset list Reset i8042 before probing because of insufficient BIOS initialisation of the i8042 serial controller. This makes Synaptics touchpad detection possible. Without resetting the Synaptics touchpad is not detected because there are always NACK messages from AUX port.
