From 27e66635016fc5bd3d36355daedf741f0a7329bb Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Tue, 15 Dec 2015 23:56:20 +0900 Subject: [PATCH] ALSA: oxfw: reuse driver entry to detect quirks Currently, assignment to model-dependent quirk is corresponding to asynchronous transactions on IEEE 1394 bus. This is also achieved with device entry. This commit changes the processing of model-dependent quirk with the entry. As a result, the transactions are sent only for Loud models.
