Subject: [PATCH 3.4 23/39] ALSA: 6fire: Fix probe of multiple cards
Date: Tue, 26 Nov 2013 16:56:47 -0800	[thread overview]
Message-ID: <20131127005620.650236165@linuxfoundation.org> (raw)
In-Reply-To: <20131127005619.011763867@linuxfoundation.org>

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@suse.de>

commit 9b389a8a022110b4bc055a19b888283544d9eba6 upstream.

The probe code of snd-usb-6fire driver overrides the devices[] pointer
wrongly without checking whether it's already occupied or not.  This
would screw up the device disconnection later.

Spotted by coverity CID 141423.
