Subject: drm/i915: Move ilk_pipe_pixel_rate() to intel_display.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ceb993201cf270a178671611a15a3b2037434ef1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Move ilk_pipe_pixel_rate() to intel_display.c

Move ilk_pipe_pixel_rate() next to its only caller
(intel_crtc_compute_pixel_rate()).
