Subject: drm: Pass the display mode to drm_calc_vbltimestamp_from_scanoutpos()
X-Git-Tag: v4.0~2486^2~12^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7da903ef04851aba81e4ddabf65c15fb71b7ce47;p=platform%2Fkernel%2Flinux-amlogic.git

drm: Pass the display mode to drm_calc_vbltimestamp_from_scanoutpos()

Rather than using crtc->hwmode, just pass the relevant mode to
drm_calc_vbltimestamp_from_scanoutpos(). This removes the last hwmode
usage from core drm.
