[PATCH v2 0/4] AsoC: Phase out hybrid PCI devres
Posted by Philipp Stanner 8 months ago
Changes in v2:
  - sof: simplify return. (Andy)
  - intel/atom: simplify return. (Andy)
  - Send a separate series for AsoC. (Andy)
  - intel/atom: Add another patch that switches EINVAL to ENOMEM. (Andy)

Hi,

a year ago we spent quite some work trying to get PCI into better shape.
Some pci_ functions can be sometimes managed with devres, which is
obviously bad. We want to provide an obvious API, where pci_ functions
are never, and pcim_ functions are always managed.

Thus, everyone enabling his device with pcim_enable_device() must be
ported to pcim_ functions. Porting all users will later enable us to
significantly simplify parts of the PCI subsystem. See here [1] for
details.

This patch series does that for sound.

Feel free to squash the commits as you see fit.

Philipp Stanner (4):
  ASoC: sof: Use pure devres PCI
  ASoC: intel/avs: Use pure devres PCI
  AsoC: intel/atom: Use pure devres PCI
  AsoC: intel/atom: Return -ENOMEM if pcim_iomap() fails

Nitpick: the scopes used in commit titles do not match recommendations. 
Below the suggested ones:
	'ASoC: Intel: atom:' for the atom-driver
	'ASoC: Intel: avs:' for the avs-driver
