Subject: drm/omap: use vblank hooks in struct drm_crtc_funcs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0396162ab9c571ee31f01866cbf168066dbf395d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/omap: use vblank hooks in struct drm_crtc_funcs

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers.  For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
