[PATCH 0/4] drm/plane: Remove drm_plane_init(), plus other cleanups

[Thomas Zimmermann <tzimmermann@suse.de>]

This patchset does cleanups to the plane code, most noteably it removes
drm_plane_init(). The function is a small wrapper, which can easily be
inlined into the few callers. Patch #1 fixes this.

The other clean-up patches #2 to #4 affect plane creation. Modesetting
helpers and nouveau share some plane-allocation code that can be shared as
helper function. While the function is already outdated, it's now at least
well documented. As suggested by Daniel, patch #3 adds a warning to
non-atomic plane helpers when they are being called from atomic drivers.
Patch #4 adds an initializer macro for non-atomic plane functions. It
should not be used in new drivers, but at least documents the current
practice.

Tested with nouveau on Nvidia G72 hardware.

A possible next step would be the inlining of drm_crtc_init() and the
removal of drm_plane.format_default.

Thomas Zimmermann (4):
  drm/plane: Remove drm_plane_init()
  drm/plane: Allocate planes with drm_universal_plane_alloc()
  drm/plane-helper: Warn if atomic drivers call non-atomic helpers
  drm/plane-helper: Provide DRM_PLANE_NON_ATOMIC_FUNCS initializer macro
