Subject: [PATCH] drm/i915: improve assert_panel_unlocked
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Fix assert_panel_unlocked for vlv/chv, and improve it a bit for
non-LVDS. Also don't pretend it works for DDI. There's still work to do
to get this right for eDP on PCH platforms, but this is a start.

v2: WARN_ON(HAS_DDI)
