Subject: cpufreq: Fix unsigned variable being checked for negative value
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5df6055939f295d723871d9781e73495b131b3d6;p=linux-beck.git

cpufreq: Fix unsigned variable being checked for negative value

clk_round_rate() returns singed value which was assigned to an unsigned
variable.
So it can't be checked for negative.
