Subject: [PATCH] blackfin-cpufreq: Change return type of cpu_set_cclk() to
 that of clk_set_rate()

From: Markus Elfring <elfring@...rs.sourceforge.net>

The return type "unsigned long" was used by the cpu_set_cclk() function
while the type "int" is provided by the clk_set_rate() function.
Let us make this usage consistent.

This issue was detected by using the Coccinelle software.
