ALSA: hdsp - Fix potential Oops in snd_hdsp_info_pref_sync_ref()
Dan Carpenter reported that setting 0 to uinfo->value.enumerated.items in snd_hdsp_info_pref_sync_ref() may lead to Oops. This function should return an error immediately in such a case instead. Cc: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
