[alsa-devel] [PATCH v2 0/9] ALSA: usb-audio: Refactor set_format()

This is a low-priority series (applies against current for-next).
This series refactors set_format() and moves the sync endpoint
initilization code into separate function. The quirks for
implicit feedback are moved to a separate function as well.
The intended result is code that is easier to read without
Changes from v2:
* Cleaned up the patchset, indentations and whitespace fixes.
* Patch #2: removed early returns when subs->sync_endpoint is already set.
This change now follows original semantics.
* Patch #9: I first corrected it thanks to Clemens Ladisch's feedback, but
then I wasn't sure if it improves anything, so I dropped it entirely.
* Dropped patch #10. Instead, added patch (now #9) to WARN_ON and return
NULL in snd_usb_add_endpoint. Otherwise, the check should be done at each
call site, and it "shouldn't happen" anyway.
