Subject: [PATCH] drm/i915: Fix DSI TE max_vblank_count handling
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
commit 33267703df15 ("drm/i915/dsi: Enable software vblank counter")
claims to get the mode_flags from the crtc_state, but in fact does
not. Fix it to do it right.
