Subject[PATCH 4.7 175/186] MIPS: Fix r4k clockevents registration
Date
4.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Huacai Chen <chenhc@lemote.com>

commit 6dabf2b7a597a9613f0b8a2fcbe01e2a0a05c896 upstream.

CPUFreq need min_delta_ticks/max_delta_ticks to be initialized, and
this can be done by clockevents_config_and_register().
