Use kvfree() to free bo->sgts, because the memory is allocated with kvmalloc_array() in panfrost_mmu_map_fault_addr().
Fixes: 187d2929206e ("drm/panfrost: Add support for GPU heap allocations") Cc: stable@vger.kernel.org Signed-off-by: Denis Efremov efremov@linux.com --- Change in v2: - kvfree() fixed in panfrost_gem_free_object(), thanks to Steven Price
