Subject: ALSA: line6: Don't forget to call driver's destructor at error path
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eedd0e95d355c7bc09df1481ef92511f631832b3;p=linux-beck.git

ALSA: line6: Don't forget to call driver's destructor at error path

Currently disconnect callback is used as a driver's destructor, and
this has to be called not only at the disconnection time but also at
the error paths during probe.
