checkpatch: comment ends inside strings is most likely not an open comment
When we are detecting whether a comment is open when we start a hunk we

However if the hunk contains something like below, then we will assume
that a comment was open. Update this heuristic to see if the comment edge
is obviously within double quotes and ignore it if so:
