Subject: drm/i915: dynamically set up bsd ring functions and params
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=58fa3835874bc3466e84e3bba6057f43acd6eb18;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: dynamically set up bsd ring functions and params

The same treatment for the bsd ring. Again, this will be split up
further by the irq rework.
