drm/i915: Don't leak in i915_gem_shmem_pread_slow()
It seems to me that we are leaking 'user_pages' in drivers/gpu/drm/i915/i915_gem.c::i915_gem_shmem_pread_slow() if read_cache_page_gfp() fails. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Dave Airlie <airlied@redhat.com>
