ALSA: Fix uninintialized error return
Static analysis with cppcheck found the following error: [sound/core/init.c:118]: (error) Uninitialized variable: err ..this was introduced by commit 2471b6c80a70e80de69f5ff4c37187c3912e5874 ("ALSA: info: Register proc entries recursively, too") where the call to snd_info_card_register was removed and no longer setting the error return in err. When snd_info_create_card_entry fails to allocate a an entry, the error path exits with garbage in err. Fix is to return -ENOMEM if entry fails to be allocated. Fixes: 2471b6c80a ("ALSA: info: Register proc entries recursively, too") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
