Please resend the patches with the git commit id in the changelog
somewhere, as is normally done (there are thousands of examples on the
mailing list.)

Also be sure that you are also backporting the patches to newer kernel
releases so that someone does not upgrade and have a regression (i.e. if
a patch is also needed in 5.15.y send a backport for that too.)

Thanks,
