From: Alexey Klimov <klimov.linux@xxxxxxxxx>
This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 479a932982944786269296a31682e5642f87b89a upstream.
Patch removes unneeded container_of() macro in exynos4_local_timer_setup().
Instead let's pass mevt pointer to setup and stop functions from
exynos4_mct_cpu_notify() and let them get evt pointer.
Tested on odroid-xu3.
