From 33b54ea1109721dcd07d3f7ee753c07482021eed Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 24 Oct 2017 08:16:48 -0700 Subject: [PATCH] drm/vc4: 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.
