Subject: Input: ALPS - move {addr,nibble}_command settings into alps_set_defaults()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=50e8b2162feb851f5af1372ba996640ad8d66fc9;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Input: ALPS - move {addr,nibble}_command settings into alps_set_defaults()

This allows alps_identify() to override these settings based on the
device characteristics, if it is ever necessary.
