Subject: drm/i915: Use fb modifiers in intel_pin_and_fence_fb_obj
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7b911adc924e0ca817ce6454ca3df922dc5d47fa;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Use fb modifiers in intel_pin_and_fence_fb_obj

And at the same time replace BUG() with a warning and handle it gracefuly.
