Message-ID: <1613540538-23792-5-git-send-email-vincent.cheng.xh@renesas.com>

Subject: [PATCH v3 net-next 4/7] ptp: ptp_clockmatrix: Clean-up dev_*() messages.
From: Vincent Cheng <vincent.cheng.xh@...esas.com>
Code clean-up.
* Remove unnecessary \n termination from dev_*() messages.
* Remove 'char *fmt' to define strings to stay within 80 column
limit. Not needed since coding guidelines increased to
100 columns limit.
Keeping format in place allows static code checkers to
validate the arguments.
* Tighten up vertical spacing.
