[PATCH 3/5] drm/i915: Clarify sprite plane function names (v3)

Matt Roper
2014-12-16T00:23:41Z

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)
