This series of patches makes sure that the existing consumers of
the infrastructure unbind their interface before they begin
destroying the driver, moves duplicated members from the
instanced component structures into a new parent structure and
introduces locking so that consumers of the interface do not use
stale data.

v2:
 - Correct application of sizeof to pointer flagged by kernel test robot

Simon Trimmer (7):
  ALSA: hda: cs35l56: Component should be unbound before deconstruction
  ALSA: hda: cs35l41: Component should be unbound before deconstruction
  ALSA: hda/tas2781: Component should be unbound before deconstruction
  ALSA: hda: hda_component: Introduce component parent structure
  ALSA: hda: hda_component: Change codecs to use component parent
    structure
  ALSA: hda: hda_component: Move codec field into the parent
  ALSA: hda: hda_component: Protect shared data with a mutex

The first three patches look rather like independent fixes.
Could you split those out and add proper Fixes tags, so that stable
trees can pick up?

The rest are a code refactoring and additional protection of the
mutex.


thanks,

Takashi
