[alsa-devel] [PATCH 00/14] Refactoring ALSA core device management

[Takashi Iwai]

Hi,

this is a series of relatively small patches for refactoring the ALSA
core device management.  I experimented a similar thing some time ago
but didn't merge it in the end due to too intrusive changes.  At this
time, the approach is rather minimalistic: only the device
registration part is replaced by embedding the struct device into
each ALSA device object.

To the outside of ALSA core, there shouldn't be many visible changes.
The only possible breakage would be an access to some renamed /
dropped fields by a downstream driver.  But it must be easy to
correct.

Some patches in the series are merely cleanup patches that can be
applied individually, but included just for completeness.

The whole patches are found in test/snd-device branch of sound git
tree, too.
