[PATCH 2/3] checkpatch: rename variables to avoid confusion

Jean Delvare
2017-09-02T15:53:49Z

The variable name "$msg_type" is sometimes used to set the message
type, and sometimes used to set the message level. This works but is
kind of confusing. Use "$msg_level" in the latter case instead, to
make the code clearer.
