From 4a3b8769f8b847d1dc3c0c14a0b0e1878be2d01c Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Tue, 23 Dec 2014 10:41:51 -0800 Subject: [PATCH] drm/i915: Clarify sprite plane function names (v4) A few of the sprite-related function names in i915 are very similar (e.g., intel_enable_planes() vs intel_crtc_enable_planes()) and don't make it clear whether they only operate on sprite planes, or whether they also apply to all universal plane types. Rename a few functions to be more consistent with our function naming for primary/cursor planes or to clarify that they apply specifically to sprite planes: - s/intel_disable_planes/intel_disable_sprite_planes/ - s/intel_enable_planes/intel_enable_sprite_planes/ Also, drop the sprite-specific intel_destroy_plane() and just use the type-agnostic intel_plane_destroy() function. The extra 'disable' call that intel_destroy_plane() did is unnecessary since the plane will already be disabled due to framebuffer destruction by the point it gets called. v2: Earlier consolidation patches have reduced the number of functions we need to rename here. v3: Also rename intel_plane_funcs vtable to intel_sprite_plane_funcs for consistency with primary/cursor. (Ander) v4: Convert comment for intel_plane_destroy() to kerneldoc now that it is no longer a static function.
