From 2ba34e43ba0469086d1ff81c13a9aa9070c1a0e1 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 22 Sep 2011 14:38:58 +0100 Subject: ALSA: fm801: Fix double free in case of error in tuner detection Commit 9676001559fce06e37c7dc230ab275f605556176 ("ALSA: fm801: add error handling if auto-detect fails") added incorrect error handling. Once we have successfully called snd_device_new(), the cleanup function fm801_free() will automatically be called by snd_card_free() and we must *not* also call fm801_free() directly.

As a bonus, this should fix init and cleanup for the case where the tuner is explicitly disabled.

When they are identical, detecting the line_jack_present flag screws up the auto-mute because alc_line_automute() is called unconditionally at initialization while it won't be triggered by unsol events, thus the old line_jack_present flag is kept for the whole run. For fixing this buggy behavior, the driver needs to check whether the line-outs are really individual, and skip if same as headphone jacks.
