Via p_chmask/c_chmask the user can define whether uac2 shall support
playback and/or capture. This has only effect on the created ALSA device,
but not on the USB descriptor. This patch adds playback/capture descriptors
dependent on that parameter.

unfortunately doesn't apply:

Please rebase on testing/next after a couple hours

I've checked the reason for which you are experiencing the conflict and
what I can see is that your testing/next branch [1] (currently based on 
v4.18-rc6) lacks two uac2 fixes which already reached vanilla master via
v4.18-rc6+ merge commit [2]:

$ git log --oneline --right-only --cherry-pick \
  balbi/testing/next..linux/master drivers/usb/gadget/function/f_uac2.c
eec24f2a0d4d usb: gadget: f_uac2: fix endianness of 'struct cntrl_*_lay3'
e87581fe0509 usb: gadget: f_uac2: fix error handling in afunc_bind (again)

So, the conflicts are caused by an older state of testing/next
relative to mainline. If I rebase [3] on top of [1], you will then face
additional conflicts when rebasing [1] on top of v4.18.

Let me know if we are on the same page.

Best regards,
Eugeniu.

[3] https://patchwork.kernel.org/patch/10480073/

I can see that the testing/next branch is still based on v4.18-rc6.
Could you please feedback if you are going to rebase it to a later -rc,
so that patch "[6/7] usb: gadget: f_uac2: disable IN/OUT ep if unused"
from my series applies without conflicts?

This patch (i.e. [3] above) now applies cleanly on top of your
testing/next branch (since the latter is rebased against v4.19-rc1).

Since there are no conflicts anymore, I hope you can pick the patch.

Many thanks in advance.

Best regards,
Eugeniu.
