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.

After this following entry in todo.rst is done?

"
struct drm_gem_object_funcs
---------------------------

GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.

We also need a 2nd version of the CMA define that doesn't require the
vmapping to be present (different hook for prime importing). Plus this needs to
be rolled out to all drivers using their own implementations, too.
"

If yes, then delete it too.

This should only say that .gem_prime_mmap() is left in struct
drm_drivers for conversion.

This sounds like it got fixed in the recent CMA clean-up series. There
are CMA initializer macros for drivers with and without vmap. I have to
take a closer look, but I think it can be removed.

Thanks for bringing this up.
