Subject: drm/i915: Correct MIPI operation mode as per expected values from VBT
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dfba2e2d3302b509fbf8bccd71ca5b2e0b47fefa;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

drm/i915: Correct MIPI operation mode as per expected values from VBT

In VBT fields operation mode is 0 for Video mode and 1 for command mode.
This field will be directly used as is in generic panel driver. So
adjust accordingly.
