These warnings are produced by kernel-doc tool:

Since this is a "move files around" commit that renames u_uac1.c to
u_uac1_legacy.c, and the warnings already exist before this commit, so
this is a false report. Sorry for this.
We introduced a new feature into the bot recently to bisect old
document warnings, but it is not working very smoothly and produces some
false reports. The "steps to reproduce" was not updated in time,
either. We are investigating these issues and will fix them soon.
Apologies again for any noise reports.
Best Regards,
Yujie
