Subject: [ 45/45] ALSA: usb-audio: 6fire: return correct XRUN indication

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eldad Zack <eldad@...refinery.com>

commit be2f93a4c4981b3646b6f98f477154411b8516cb upstream.

Return SNDRV_PCM_POS_XRUN (snd_pcm_uframes_t) instead of
SNDRV_PCM_STATE_XRUN (snd_pcm_state_t) from the pointer
function of 6fire, as expected by snd_pcm_update_hw_ptr0().

Caught by sparse.
