[PATCH] alsa: Fix device reservation fails when a device string has seperator(, )

[jeongyeon.kim@xxxxxxxxxxx (KimJeongYeon)]

For example, the device parameter of pa_alsa_get_reserve_name() is "hw:USB,0",
snd_card_get_index() always fails. Because seperator(,) wasn't regarded.
Therefore, JACK couldn't obtain audio device from Pulseaudio.
