X-Git-Tag: upstream/snapshot3+hdmi~12689^2~679^2~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b1a78858c4579d678444c007617292ccf6f7a315;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

During rate scale, reset starting action after making action adjustment
to avoid the possibility of break out of loop too early.
