5.17.6 has commit 60d2b0b1018a ("objtool: Fix code relocs vs weak
symbols"), which has a known issue that is fixed with commit
ead165fa1042 ("objtool: Fix symbol creation"). If you apply ead165fa1042
on 5.17.6 or newer, does that resolve your issue?
ead165fa1042 is tagged for stable but I don't think Greg picks up
patches from mainline until they are in a tagged -rc release.
Cheers,
