drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver
Several GEM and PRIME callbacks have been deprecated in favor of per-instance GEM object functions. Remove the callbacks as they are now unused. The only exception is .gem_prime_mmap, which is still in use by several drivers. What is also gone is gem_vm_ops in struct drm_driver. All drivers now use struct drm_gem_object_funcs.vm_ops instead. While at it, the patch also improves error handling around calls to .free and .get_sg_table callbacks. v3: * restore default call to drm_gem_prime_export() in drm_gem_prime_handle_to_fd() * return -ENOSYS if get_sg_table is not set * drop all checks for obj->funcs * clean up TODO list and documentation v2: * update related TODO item (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200923102159.24084-23-tzimmermann@suse.de
