It was on top of 6.18-rc1, but should apply fine on 6.17.5
Tried myself, saved the email as patch.eml and applied with patch:

mnyman@mnyman-desk:~/src/linux-stable$ git reset --hard v6.17.5
HEAD is now at 99efbd4259f3 Linux 6.17.5

mnyman@mnyman-desk:~/src/linux-stable$ patch -p1 < ~/src/usb/patch/early/patch.eml

patching file drivers/usb/early/xhci-dbc.c
(Stripping trailing CRs from patch; use --binary to disable.)
patching file drivers/usb/early/xhci-dbc.h

git am also works as it should

mnyman@mnyman-desk:~/src/linux-stable$ git reset --hard v6.17.5
HEAD is now at 99efbd4259f3 Linux 6.17.5

mnyman@mnyman-desk:~/src/linux-stable$ git am ~/src/usb/patch/early/patch.eml

Maybe you still have some custom dbc hacks on top of 6.17.5 while patching?

Thanks
