Subject: drm/xe/vf: Don't apply tile workarounds if VF
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f20535ce1dd96003e76c958ffaa9c345483d2dfd;p=users%2Fjedix%2Flinux-maple.git

drm/xe/vf: Don't apply tile workarounds if VF

The VF drivers can't apply any workarounds as they don't have
access to related registers. Since xe_wa_apply_tile_workarounds()
function is not using RTP yet, we have to add early return.
