This chain of patches does some clearing up and add capture support to the compressed API.
Missing is support for capture streams that don't use the copy callback. Also I have included two patches at the end of the chain that remove the buffer pointers and just use the cumulative values however as our setup uses the copy callback these are untested past build so should be taken with caution.
Thanks, Charles
Thess patches apply to: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git branch "for-next"
based on top of commit 126825e ALSA: snd-usb: add quirks handler for DSD streams
Vinod, Pierre, could you guys check these patches?
If these are OK, I can still merge for 3.10. Although it's already late for 3.10, there are little users of compress stuff, so the impact must be fairly small. If you guys aren't still happy, let's postpone for 3.11.
If we really merge it, don't you mind me merging soc-compress patch in my tree (directly to for-next branch), Mark?
thanks,
Takashi
