[alsa-devel] [PATCH 16/30] ALSA: speakers: Rename to oxfw and rename some members

Takashi Sakamoto o-takashi at sakamocchi.jp
Fri Nov 28 16:59:25 CET 2014


This commit renames 'firewire-speakers' to 'oxfw' to enhance support for
devices which based on OXFW970/971. A line for MODULE_ALIAS is added.

Additionally, to help for works in followed paches, some members
in private structure are renamed.
