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.
