Subject[PATCH 3.2 029/153] ASoC: nuc900: Fix a loop timeout test
3.2.102-rc1 review patch.  If anyone has any objections, please let me know.

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

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

commit 65a12b3aafed5fc59f4ce41b22b752b1729e6701 upstream.

We should be finishing the loop with timeout set to zero but because
this is a post-op we finish with timeout == -1.

Fixes: 1082e2703a2d ("ASoC: NUC900/audio: add nuc900 audio driver support")
