From 4e974c120039e35b90d2cb0459452bd9a6a71594 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 3 Nov 2017 12:21:48 -0700 Subject: [PATCH] Input: convert autorepeat timer 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.
