From ee03e3f00566201ea91d90430dc43bd08c7e9eef Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 24 Oct 2017 09:44:48 -0700 Subject: [PATCH] Input: touchsceen - convert timers to use timer_setup() In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.
