This patch breaks suspend/resume on Samsung Exynos5250 Snow Chromebook. 
It looks that it is waiting forever(?) on some cros ec i2c call. With 
no_console_suspend and initcall_debug kernel parameters together with 
playing with magic-sysrq after suspend/resume cycle I've managed to get 
following log:
