Subject: [PATCH] ASoC: nuc900: Fix a loop timeout test
Git-commit: 65a12b3aafed5fc59f4ce41b22b752b1729e6701
Patch-mainline: v4.16-rc1
References: bsc#1051510
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")
