Subject: [PATCH 08/11] [media] em28xx-audio: Properly report failures to start stream
Date: Sun, 19 Jun 2011 14:42:40 -0300 [thread overview]
Message-ID: <20110619144240.24cec9ac@pedra> (raw)
In-Reply-To: <cover.1308503857.git.mchehab@redhat.com>
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.
