Subject: [alsa-devel] [PATCH] ALSA: usb-audio: Fix memory leak in __snd_usbmidi_create
Date: Sun, 27 Oct 2019 17:10:06 -0500 [thread overview]
Message-ID: <20191027221007.14317-1-navid.emamdoost@gmail.com> (raw)
In the implementation of __snd_usbmidi_create() there is a memory leak
caused by incorrect goto destination. Go to free_midi if
snd_usbmidi_create_endpoints_midiman() or snd_usbmidi_create_endpoints()
fail.
Fixes: 731209cc0417 ("ALSA: usb-midi: Use common error handling code in __snd_usbmidi_create()")
