[alsa-devel] [PATCH RFC 0/5] Add devres support to card resources

[Takashi Iwai]

Hi,

the devres or device-managed resource allocation is a popular method
among many drivers but we didn't have such a mechanism for the core
sound card objects.  Here is an attempt to implement that.

The first patch gives the devm-version of page allocator helper, and
the second patch provides the devm-version of snd_card_new().
The rest patches are examples of the new API usages.

As of now, this patch series is still an RFC.  The usefulness of this
is still unclear, but I believe this can be used in all legacy ALSA
drivers pretty well.  For ASoC, this would help very little,
supposedly, though.

The latest patches are found in topic/devres branch of my sound.git
tree, too.


thanks,

Takashi
