From 056622053b8ae02978678ac1321b5bd956e7c812 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 12 Feb 2015 13:43:22 +0100 Subject: ALSA: seq: Define driver object in each driver This patch moves the driver object initialization and allocation to each driver's module init/exit code like other normal drivers. The snd_seq_driver struct is now published in seq_device.h, and each driver is responsible to define it with proper driver attributes (name, probe and remove) with snd_seq_driver specific attributes as id and argsize fields. The helper functions snd_seq_driver_register(), snd_seq_driver_unregister() and module_snd_seq_driver() are used for simplifying codes.
