Subject: sh: remove bogus highest / lowest logic from clock rate rounding
X-Git-Tag: v2.6.37-rc1~136^2~93
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=088bcc2aff25f31f1497f8196fa02c8cd2a43f68;p=karo-tx-linux.git

sh: remove bogus highest / lowest logic from clock rate rounding

The use of highest and lowest in clk_rate_table_round() is completely bogus
and superfluous. Remove it.
