Merge branch 'drm-fixes-3.8' of git://people.freedesktop.org/~agd5f/linux into drm-next
Fixes for UMS mode which has been broken for a while plus an rn50 fix and a dma fix. * 'drm-fixes-3.8' of git://people.freedesktop.org/~agd5f/linux: radeon/kms: fix dma relocation checking radeon/kms: force rn50 chip to always report connected on analog output drm/radeon: fix error path in kpage allocation drm/radeon: fix a bogus kfree drm/radeon: fix NULL pointer dereference in UMS mode
