From 5ce8cc48443596e500586007b443e1eea6334efc Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Tue, 15 Dec 2015 23:56:21 +0900 Subject: [PATCH 5/5] ALSA: oxfw: gather model-dependent conditions to a function Adding control elements is just for models supported by old firewire-speakers modules. The processing should be in a function to add model-dependent quirk. This commit moves the codes to the function. As a result, the function should handle error state, thus this commit also changes prototype of the function.
