Subject[PATCH 3.13.y-ckt 08/90] Input: synaptics - split synaptics_resolution(), query first
Date
3.13.11-ckt20 -stable review patch.  If anyone has any objections, please let me know.

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

From: Daniel Martin <consume.noise@gmail.com>

commit 8b04baba10b007f8b6c245a50be73cf09cc3a414 upstream.

Split the function synaptics_resolution() into synaptics_resolution() and
synaptics_quirks(). synaptics_resolution() will be called before
synaptics_quirks() to query dimensions and resolutions before overwriting
them with quirks.
