ASoC: mchp-spdifrx: fix return value in case completion times out
[ Upstream commit a4c4161d6eae3ef5f486d1638ef452d9bc1376b0 ]
wait_for_completion_interruptible_timeout() returns 0 in case of
timeout. Check this into account when returning from function.
Fixes: ef265c55c1ac ("ASoC: mchp-spdifrx: add driver for SPDIF RX")
