[Linux-kernel-mentees] [PATCH] checkpatch: avoid COMMIT_LOG_LONG_LINE warning for signature tags

Currently checkpatch warns us for long lines in commits even for
signature tag lines.
E.g., running checkpatch on commit 4bbdfe25600c ("IB/opa_vnic: Properly
clear Mac Table Digest") reports this warning:
WARNING: Possible unwrapped commit description (prefer a maximum 75 chars per line)
Reviewed-by: Niranjana Vishwanathapura <niranjana.vishwanathapura at intel.com>
This is an example of false positive. Provide a fix by excluding
signature tag lines from this class of warning.
