Subject: i8042: Add keyboard enable logic in kbd_reset()
X-Git-Tag: v2015.07-rc1~272
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=f9f788f0721350e594ce3e7978968847b057afc1;p=u-boot

i8042: Add keyboard enable logic in kbd_reset()

This code appears to be missing a piece that is needed on some keyboards
to enable the keyboard. Add this in.

This makes the keyboard work correctly on chromebook_link.
