Subject: [ARM] omap: remove unnecessary calls to propagate_rate()
X-Git-Tag: firefly_0821_release~15211^2~20^2~73
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a9e882096317a088087b608d272da7029a6cc8c8;p=firefly-linux-kernel-4.4.55.git

[ARM] omap: remove unnecessary calls to propagate_rate()

We've always called propagate_rate() in the parent function to
the .set_rate methods, so there's no point having the .set_rate
methods also call this heavy-weight function - it's mere
duplication of what's happening elsewhere.
