Re: [PATCH 4/4] input: dynamically allocate ABS information

From: Dmitry Torokhov
Date: Wed Jul 21 2010 - 04:32:19 EST


Input: switch to input_abs_*() access functions

From: Daniel Mack <daniel@xxxxxxxx>

Change all call sites in drivers/input to not access the ABS axis
information directly anymore. Make them use the access helpers instead.

Also use input_set_abs_params() when possible.
Did some code refactoring as I was on it.
