[PATCH v3 23/23] drm: zte: use vblank hooks in struct drm_crtc_funcs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shawn Guo <shawn.guo@xxxxxxxxxx>

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.

The functions are moved around to save forward declaration.
