[Intel-gfx] [PATCH 1/2] drm/i915: set CPT FDI RX polarity bits based on VBT

From: Paulo Zanoni Check the VBT to see if the machine has inverted FDI RX polarity on CPT. Based on this bit, set the appropriate bit on the TRANS_CHICKEN2 registers. This should fix some machines that were showing black screens on all outputs. Cc: sta...@vger.kernel.org Bugzilla: https://bugs
