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

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

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 44008f0896ae205b02b0882dbf807f0de149efc4 upstream.

Smatch complains that we have nested checks for "spdif_present".  It
turns out the current behavior isn't correct, we should remove the first
check and keep the second.

Fixes: 1077a024812d ('ALSA: hda - Use generic parser for Cirrus codec driver')
