From 2c9a9cfec04f2c6ed7b4e607cd53ca903b2c4642 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 8 Oct 2014 09:28:32 -0700 Subject: Input: automatically set EV_ABS bit in input_set_abs_params Let's automatically set EV_ABS bit in device's event type list when calling input_set_abs_params() so that drivers do not have to do it explicitly. These calls are never in a hot paths so we won't lose much time by setting the same bit several times.
