Richard Fitzgerald 28b329f431 ALSA: hda: hda_component: Fix mutex crash if nothing ever binds 
Move the initialization of parent->mutex into
hda_component_manager_init() so that it is always valid.

In hda_component_manager_bind() do not clear the parent information.
Only zero-fill the per-component data ready for it to be filled in
by the components as they bind.

Previously parent->mutex was being initialized only in
hda_component_manager_bind(). This meant that it was only
initialized if all components appeared and there was a bind callback.
If there wasn't a bind the mutex object was not valid when the
Realtek driver called any of the other functions.
