From caa751bad444268d756b48ca03d7cceda3430cc8 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 25 Feb 2014 08:30:50 +0100 Subject: ALSA: Create sysfs attribute files via groups Instead of calling each time device_create_file(), create the groups of sysfs attribute files at once in a normal way. Add a new helper function, snd_get_device(), to return the associated device object, so that we can handle the sysfs addition locally. Since the sysfs file addition is done differently now, snd_add_device_sysfs_file() helper function is removed.
