Subject: drm/st: Remove drm_api struct from drivers
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=64849d1236e33b3325e00167c97119af52990ad8;p=mesa.git

drm/st: Remove drm_api struct from drivers

	Remove the drm_api from the functions in the softpipe and
	i915simple drivers. Create wrapper functions in the
	backends instead.
