[0/2] drm: Remove gem_prime_mmap callback

Message

Thomas Zimmermann June 13, 2023, 2:51 p.m. UTC

Remove the gem_prime_mmap callback from struct drm_driver. Rework
msm, which has its own implementation. Then remove the callback and
call drm_gem_prime_mmap() directly. This closes a long-standing item
on the TODO list.

The change removes the last GEM callback from the driver structure.
GEM memory managers should implement the callbacks in struct dma_buf_ops
and struct drm_gem_object_funcs to adapt the DRM to their needs.

Thomas Zimmermann (2):
  drm/msm: Initialize mmap offset after constructing the buffer object
  drm: Remove struct drm_driver.gem_prime_mmap
