This simplifies the code as locking is handled by the Xarray internally and removes the need for a seperate mutex to proect the IDR. The patches are from this tree and have been rebased to drm-next-2025-06-06 https://git.infradead.org/?p=users/willy/xarray.git;a=shortlog;h=refs/heads/xarray-conv The series has been compiled and tested with drivers/gpu/drm/tests/.kunitconfig and passes all tests.
