Subject: [PATCH 3.17 145/319] MIPS: loongson2_cpufreq: Fix CPU clock rate setting mismerge
3.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aaro Koskinen <aaro.koskinen@....fi>
commit aa08ed55442ac6f9810c055e1474be34e785e556 upstream.
During 3.16 merge window, parts of the commit 8e8acb32960f
(MIPS/loongson2_cpufreq: Fix CPU clock rate setting) seem to have
been deleted probably due to a mismerge, and as a result cpufreq
is broken again on Loongson2 boards in 3.16 and newer kernels.
Fix by repeating the fix.
