From d7da3a3ccdeb64ceedb51b0a3377ba56cc2999fa Mon Sep 17 00:00:00 2001 From: Ping Cheng Date: Fri, 13 Jun 2014 13:37:33 -0700 Subject: Input: wacom - cleanup multitouch code when touch_max is 2 Historically we dealt with touch_max equals to 2 differently from other MT devices. Now we use input_mt_*() to process all MT events, as long as touch_max is greater than 1. So, there is no need to take (touch_max == 2) as a special case any more.

The difference is if the reads/writes are done in native or little endian. But for byte reads/writes there is no difference so this does not matter for inb/outb - and this driver only uses the byte variants. Signed-off-by: Sam Ravnborg Signed-off-by: David S.
