ALSA: bebob: change type of substream counter from atomic_t to unsigned int
The counter is incremented/decremented in critical section protected with mutex. Therefore, no need to use atomic_t. This commit changes the type to unsigned int. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
