From e9985b96e1505dda3207b8addac47c3a45a8e776 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 28 Oct 2013 11:24:23 +0100 Subject: [PATCH] ALSA: 6fire: Fix probe of multiple cards 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.
