Subject: OPP: Pass rounded rate to _set_opp()
From: Viresh Kumar <viresh.kumar@xxxxxxxxxx>
commit 7269c250db1b89cda72ca419b7bd5e37997309d6 upstream.
The OPP core finds the eventual frequency to set with the help of
clk_round_rate() and the same was earlier getting passed to _set_opp()
and that's what would get configured.
The commit 1efae8d2e777 ("OPP: Make dev_pm_opp_set_opp() independent of
frequency") mistakenly changed that. Fix it.
Fixes: 1efae8d2e777 ("OPP: Make dev_pm_opp_set_opp() independent of frequency")
