drm/radeon: Fix sparc regression in r300_scratch()
Commitb4fe945405
("drm/radeon: Fix memory allocation failures in the preKMS command stream checking.") added a regression in that it completely tossed the get_unaligned() done by r300_scratch() which we added in commit958a6f8ccb
("drm: radeon: Fix unaligned access in r300_scratch()."). Put it back. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Matt Turner <mattst88@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
