Subject[PATCH v6 03/22] drm/panfrost: Put mapping instead of shmem obj on panfrost_mmu_map_fault_addr() error
Date
When panfrost_mmu_map_fault_addr() fails, the BO's mapping should be
unreferenced and not the shmem object which backs the mapping.

Cc: stable@vger.kernel.org
Fixes: bdefca2d8dc0 ("drm/panfrost: Add the panfrost_gem_mapping concept")
