I think you explained it wrong when you didn't mention this is
_only_ a problem when using --codespell.

Likely it'd be better to use "(?:^|\s)($misspellings)(?=\s|$)"

total: 0 errors, 0 warnings, 2 checks, 5 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
mechanically convert to the typical style using --fix or --fix-inplace.

t_spell.c has style problems, please review.

NOTE: If any of the errors are false positives, please report
them to the maintainer, see CHECKPATCH in MAINTAINERS.
