Subject: ALSA: hda - Decouple PCM and hwdep devices from codec object
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=327ef4f02582d01f7eedb291794106823b44a0cf;p=linux.git

ALSA: hda - Decouple PCM and hwdep devices from codec object

This is a preliminary patch for the hda_bus implementation, removing
the parent device setup to codec device.  Since the bus and the class
devices can't be crossed over, leave the sound devices to the default
parent device as is.
