Static analysis with cppcheck found the following error: [sound/core/init.c:118]: (error) Uninitialized variable: err ..this was introduced by commit 2471b6c8 ("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.
