* ALSA: oxfw: rename helper functions for duplex streamsTakashi Sakamoto2019-06-125-53/+58
| | | | | | | | | | | | In former commits, ALSA oxfw driver handles two isochronous contexts at the same time, except for some devices which supports one endpoint of isochronous packet stream. This commit renames some helper functions so that they handles duplex streams. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
