ALSA: hwdep: Take private_data as drvdata for sysfs
For referring to a different object from sysfs ops, take hwdep private_data as stored via dev_set_drvdata() at creating the device object. In that way, the same sysfs ops can be used by different device types. Signed-off-by: Takashi Iwai <tiwai@suse.de>
