Subject: [media] em28xx-audio: Properly report failures to start stream
X-Git-Tag: v3.12-rc1~5134^2~291
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=debb7241498001a0da10ee01b72f9ec1f9b1edc8;p=kernel%2Fkernel-generic.git

[media] em28xx-audio: Properly report failures to start stream

If the audio stream fails for any reason, it should:
	1) Report an error via dmesg;
	2) Mark internally that the stream didn't started.
