+MIME-Version: 1.0

+
+commit 3e206b6aa6df7eed4297577e0cf8403169b800a2 upstream.
+
+We try to filter out the corresponding xxx1 output
+if the xxx0 output is not present. But the way that is
+being done is pretty awkward. Make it less so.

+Subject: drm/i915/sdvo: Setup DDC fully before output init
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Ville Syrjälä <ville.syrjala@linux.intel.com>
+
+commit e79762512120f11c51317570519a1553c70805d8 upstream.
+
+Call intel_sdvo_select_ddc_bus() before initializing any
+of the outputs. And before that is functional (assuming no VBT)
+we have to set up the controlled_outputs thing. Otherwise DDC
+won't be functional during the output init but LVDS really
+needs it for the fixed mode setup.
+
+Note that the whole multi output support still looks very
+bogus, and more work will be needed to make it correct.
+But for now this should at least fix the LVDS EDID fixed mode
+setup.

+Subject: drm/rockchip: dsi: Force synchronous probe
+
+From: Brian Norris <briannorris@chromium.org>
+
+commit 81e592f86f7afdb76d655e7fbd7803d7b8f985d8 upstream.
+
+We can't safely probe a dual-DSI display asynchronously
+(driver_async_probe='*' or driver_async_probe='dw-mipi-dsi-rockchip'
+cmdline), because dw_mipi_dsi_rockchip_find_second() pokes one DSI
+device's drvdata from the other device without any locking.
+
+Request synchronous probe, at least until this driver learns some
+appropriate locking for dual-DSI initialization.
