Hello Felipe and linux-usb community,
This is a collection of UAC fixes, some of which have been written back
in 2016 on top of v3.14. v4.13-rc1 commit eb9fecb9e69b ("usb: gadget:
f_uac2: split out audio core") made forward-porting of these patches to
recent kernels quite painful and time-consuming, so we decided to
re-base them against v4.18-rc1, re-test and share them with community.
These changes have already undergone internal review, which includes:
* static analysis:
- checkpatch --strict, cppcheck, smatch, sparse, coccicheck, make W=1
* dynamic testing:
- Audio playback on host side and recording on gadget side, where the
latter is RCAR Gen3 Salvator-X arm64 target and the former is a
Ubuntu PC or an appropriate USB port on the same RCAR target.
The kernel was compiled with and w/o KA/UB sanitizers.
The "older" patches actually live in real Customer products.
Thank you in advance for any feedback/review comments.
Best regards,
Eugeniu.
