From 74ee0477512b56c95ad2f7b0035120ada58b88fd Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 24 Oct 2017 11:23:21 -0400 Subject: media: s2255: 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.
