[PATCH libdrm] drm: Remove create_handle() drm_framebuffer "virtual".

Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Because all drivers currently use gem objects for framebuffer planes,
the virtual create_handle() is not required. This change adds a
struct drm_gem_object *gems[4] field to drm_framebuffer and removes
create_handle() function pointer from drm_framebuffer_funcs. The
corresponding *_create_handle() function is removed from each driver.

In many cases this change eliminates a struct *_framebuffer object,
as the only need for the derived struct is the addition of the gem
object pointer.

TESTED: compiled: allyesconfig ARCH=x86,arm platforms:i915, rockchip
