I have just sent a fixup for this snafu:
https://lore.kernel.org/linux-snps-arc/20220426072447.125975-1-geomatsi@gmail.com/T/#u

IIUC, you have not yet sent a pull-request for next release. So probably
it makes sense to squash this commit with b08a66fb680018b6 ("ARC: disasm:
handle ARCv2 case in kprobe get/set functions").
