Subject: drm/radeon/ci: disable needless sclk changes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d967be9b80a5aa3ba228a9c2d3fea91ae99e4a07;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drm/radeon/ci: disable needless sclk changes

The current code always reprogrammed the sclk levels,
but we don't currently handle disp sclk requirements
so just skip it.
