[Linux-kernel-mentees] [PATCH v2] checkpatch: disable commit log length check warning for signature tag

Disable commit log length check in case of signature tag. If the commit
log line has valid signature tags such as "Reported-and-tested-by" with
more than 75 characters, suppress the long length warning.

For instance in commit ac854131d984 ("USB: core: Fix misleading driver bug
report"), the corresponding patch contains a "Reported by" tag line which
exceeds 75 chars. And there is no valid way to shorten the length.
