From a3aaf7d2bd388caea2bd0fba266b815ac708c49d Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Wed, 3 Oct 2018 08:21:51 +0900 Subject: ALSA: bebob: use managed-resource to maintain data specific to M-Audio FW-1814/ProjectMix I/O ALSA bebob driver allocates memory object for data specific to M-Audio FW-1884/ProjectMix I/O. The object is to maintain format of isochronous packet payload for packet streaming by components for ALSA rawMIDI/PCM interfaces. The object can be released as managed-resource of 'struct snd_card.card_dev'. This commit uses managed-resource of the sound card device for this purpose.
