Subject: drm/i915/vrr: Use crtc_vsync_start/end for computing vrr.vsync_start/end
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f71f86daa1b28def08bd855dd8ac3c1a9b19ae4c;p=thirdparty%2Fkernel%2Flinux.git

drm/i915/vrr: Use crtc_vsync_start/end for computing vrr.vsync_start/end

Use adjusted_mode->crtc_vsync_start/end instead of
adjusted_mode->vsync_start while computing vrr.vsync_start/end.
For most modes, these are same but for 3D/stereo modes the
crtc_vsync_start is different than vsync_start.
