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. Signed-off-by: Takashi Iwai <tiwai@suse.de>
