| Subject: ALSA: firewire-motu: fix stream format for MOTU 8pre FireWire |
| |
| From: Takashi Sakamoto <o-takashi@sakamocchi.jp> |
| |
| commit fc36ef80ca2c68b2c9df06178048f08280e4334f upstream. |
| |
| My previous refactoring for ALSA firewire-motu driver brought regression |
| to handle MOTU 8pre FireWire. The packet format is not operated correctly. |
