MIPS/loongson2_cpufreq: Fix CPU clock rate setting
Loongson2 has been using (incorrectly) kHz for cpu_clk rate. This has been unnoticed, as loongson2_cpufreq was the only place where the rate was set/get. After commit 652ed95d5fa6074b3c4ea245deb0691f1acb6656 (cpufreq: introduce cpufreq_generic_get() routine) things however broke, and now loops_per_jiffy adjustments are incorrect (1000 times too long). The patch fixes this by changing cpu_clk rate to Hz. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Cc: stable@vger.kernel.org Cc: Rafael J.
