I have a TonePort UX2 that I've used for testing, meaning that some of this is really only compile-tested.

If anyone is responsible for testing with real hardware, I'll happily review.

To be clear, the TonePort UX2 is real hardware. But this driver basically supports four classes of Line 6 devices and I'm only covering one of them.

So this series is a first step in trying to address this. Having this as a single driver probably made sense when it was a separate project, but now that it is in-tree it seems like the POD, PODHD, TonePort, and Variax pieces should each be separate drivers that each depend on a core Line 6 driver. I think the cleanup in this series will make that easier. None of this is my area of expertise, though, so advice and feedback is very welcome.

...

are there any active developers for this driver?

I intended to do further work. I know there is quite a bit of mundane checkpatch cleanup that would need to get done before this could get promoted, and I believe I read that it's using sysfs for stuff that would normally be done via an ALSA interface, and the sysfs interface has not been documented nor has it been justified. All stuff I thought I might look into.

But I'm just doing this for fun so I can't promise anything. :-)

OK, so the situation looks fairly good, we have a few active developers and/or testers. And the current code doesn't look so terrible despite of it being in staging directory. That said, I think we can promote this stuff into sound/usb/line6 directory, then apply Chris' cleanup patches, and work on it further.

Does it sound OK for you guys? Greg?

Once when I get approval, I'll start a new clean branch on sound.git tree so that you guys can work on it further for 3.20 kernel.

JFYI, I merged all patches Greg forwarded to me into topic/line6 branch of sound git tree. It's included to linux-next, so you can work on linux-next or my branch as well.

Now the code has been moved from driver/staging/line6 to sound/usb/line6. I'm going to apply some driver rename and cleanup patches to follow to other ALSA driver standards, and think of splitting to each driver with a core line6 helper module after that.

Feel free to send the further development patches to me and/or alsa-devel ML like other sound drivers.

thanks,

Takashi
