Subject: [PATCH 4.4 20/66] Input: i8042 - add Gigabyte P57 to the keyboard reset table

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kai-Heng Feng <kai.heng.feng@...onical.com>

commit 697c5d8a36768b36729533fb44622b35d56d6ad0 upstream.

Similar to other Gigabyte laptops, the touchpad on P57 requires a
keyboard reset to detect Elantech touchpad correctly.
