Subject: drm/i915/dp: Refactor common eDP lid detection
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d410b56d74bc706f414158cb0149e2a149ee1650;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/dp: Refactor common eDP lid detection

Both gmch and pch detection routines used the exact same routine for
eDP, so de-duplicate.
