Hi stable folks,
Please apply commit fc7bf4c0d65a ("drm/i915/selftests: Fix inconsistent
IS_ERR and PTR_ERR") to 5.15, where it resolves a couple of instances of
-Wuninitialized with clang-21 or newer that were introduced by commit
cdb35d1ed6d2 ("drm/i915/gem: Migrate to system at dma-buf attach time
(v7)") in 5.15.
In file included from drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c:329:
drivers/gpu/drm/i915/gem/selftests/i915_gem_dmabuf.c:105:18: error: variable 'dmabuf' is uninitialized when used here [-Werror,-Wuninitialized]
105 | PTR_ERR(dmabuf));

94 | struct dma_buf *dmabuf;
| ^
| = NULL
drivers/gpu/drm/i915/gem/selftests/i915_gem_dmabuf.c:161:18: error: variable 'dmabuf' is uninitialized when used here [-Werror,-Wuninitialized]

It applies and builds cleanly for me. If there are any issues, please
let me know.
Cheers,
Nathan
