[PATCH 2/2] staging: bcm2835-audio: Don't leak workqueue if open fails

Currently, if bcm2835_audio_open() fails partway, the allocated workqueue is leaked. Avoid that. While at it, propagate the return value of bcm2835_audio_open_connection() on failure instead of returning -1. Signed-off-by: Tuomas Tynkkynen ---
