Subject: drm/i915: correct FBC update when pipe base update occurs
X-Git-Tag: firefly_0821_release~12332^2~15
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=edb81956422c9926553bb97e3e56b849da0f4bb5;p=firefly-linux-kernel-4.4.55.git

drm/i915: correct FBC update when pipe base update occurs

We usually don't have an SAREA, and we always want to update the FBC
status anyway, so move the update up above the various master/sarea
checks.
