[PATCH v3 00/10] ALSA/ASoC: Intel: avs: HDAudio bus and general fixes

[Cezary Rojewski <cezary.rojewski@intel.com>]

The first half of the patchset concentrates on the driver initialization
procedure - a number of steps do not clean up after themselves when they
fail.  This is for both, HDAudio bus (ext) and the DSP part (avs) and
targets following procedures:

- stream initialization
- link initialization
- bus initialization

The next five are loosely related fixes.  First, split topology-loading
error handling from request-firmware one.  Currently -ENOENT coming from
topology-loading, which is a real error, is ignored.

Second, with deeper test coverage around corrupted firmware/DSP exception
handling, new issues are unearthed.  Switch to async d0ix_work
cancellation to avoid deadlock when D0IX has been scheduled just before
the recovery work.

The 09/10 patch, init_config change fixes possible out-of-bounds bug.
The fix is larger than what one could expect as instead of patching with
if-statements I've decided to refactor the parsing of init_configs.
The scenario that causes the problem no longer exists.
Note: the solution does not impose any changes on the existing topology
files (userspace).

The remaining two, IMHO are self-explanatory.

Changes in v3:
- dropped the patch introduced in v2 as an equivalent change has just
  been merged [1]

Changes in v2:
- added patch "ALSA: hda: Clean up pages when stream buffers allocation
  fails" to address Mark's review for "ASoC: Intel: avs: Clean up the
  bus when its initialization fails" and clean up pages before
  collapsing the bus initialization
- removed unused 'acomp' variable as pointed out by Mark
