From: Alexey Klimov <klimov.li...@gmail.com>
3.12-stable review patch. If anyone has any objections, please let me 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.
