Subject: drm/i915/bdw: Add BDW PCH check first
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e76e063486355d2ac42b1c6fffc5fb7166d24389;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/bdw: Add BDW PCH check first

Early platforms use the same PCH as HSW, and to avoid triggering the
!ULT, and !HSW warnings, simply put it first in the search.
