Subject: drm/i915: Switch to per-crtc vblank vfuncs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 08fa8fd0faa5716ed180e109a022e2c0f42c2e4a
Patch-mainline: v5.4-rc1
References: bsc#1152489
Switch from the driver-wide vblank vfuncs to the per-crtc ones so that
we don't have so many platform specific vfuncs in the driver struct.
We still need to do something about the rest fo the irq vfuncs...
