[PATCH v2 0/7] drm/client: Simply client-buffer interface and implementation

[Thomas Zimmermann <tzimmermann@suse.de>]

Streamline the client-buffer code and remove the drm_client_framebuffer_
functions. Makes the code easier to work with.

Also prepares for importing non-dumb-buffer objects. Most of the in-
kernel clients will use dumb-buffer allocation. In the case of the
per-driver fbdev_probe code, the client buffer can also wrap an object
that comes from a different memory region; for example gma500's stolen
memory area. This functionality is required to move forward with the
various per-driver implementations of fbdev_probe within the overall
DRM-client framework.

Tested with efidrm and virtio-gpu on Virt I/O hardware.

v2:
- fix possible NULL-pointer deref in delete
- avoid dependency on KMS helpers

Thomas Zimmermann (7):
  drm/client: Remove pitch from struct drm_client_buffer
  drm/client: Move dumb-buffer handling to
    drm_client_framebuffer_create()
  drm/client: Inline drm_client_buffer_addfb() and _rmfb()
  drm/client: Deprecate struct drm_client_buffer.gem
  drm/client: Remove drm_client_framebuffer_delete()
  drm/client: Create client buffers with drm_client_buffer_create_dumb()
  drm/client: Flush client buffers with drm_client_buffer_sync()
