Subject[PATCH v2] checkpatch: fix TYPO_SPELLING check for words with apostrophe
Date
checkpatch reports a false TYPO_SPELLING warning for some words
containing an apostrophe when run with --codespell option.

A false positive is "doesn't". Occurrence of the word causes
checkpatch to emit the following warning:

"WARNING: 'doesn'' may be misspelled - perhaps 'doesn't'?"

Modify the regex pattern to be more in line with the codespell
default word matching regex. This fixes the word capture and
avoids the false warning.

- Use the default codespell word regex.
- Modify commit message to specify --codespell usage
