Subject: [RFC PATCH 3/6] drm/i915: Propagate "_release" function name suffix down
Replace mixed "_fini"/"_cleanup"/"_cleanup_hw" suffixes found in names
of fucntions called from i915_driver_release() with "_release" suffix
consistently. This provides better code readability, especially
helpful when trying to work out which phase the code is in.
Functions names starting with "i915_driver_", i.e., those defined in
drivers/gpu/dri/i915/i915_drv.c, just have their "cleanup" or "fini"
parts of their names replaced with the "_release" suffix, while names
of functions coming from other source files have been suffixed with
"_driver_release" to avoid ambiguity with other possible .release entry
points.
