Subject: drm/i915: Introduce intel_fb_obj() macro
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=155e63696caab748da3f344f66de503038a72024;p=linux-beck.git

drm/i915: Introduce intel_fb_obj() macro

Add an intel_fb_obj() macro that returns the GEM object associated with
a DRM framebuffer.  This macro is safe to call on NULL framebuffers (a
NULL object pointer will be returned in this case).
