Subject: drm/i915: make FDI training a display function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=674cf967614f31826f45d30c8f8f8e050cc3eef2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: make FDI training a display function

Rather than branching in ironlake_pch_enable, add a new train_fdi
function to the display function pointer struct and use it instead.
