[PATCH v3 net-next 4/7] ptp: ptp_clockmatrix: Clean-up dev_*() messages.

From: vincent.cheng.xh
Date: Wed Feb 17 2021 - 01:08:08 EST


From: Vincent Cheng <vincent.cheng.xh@xxxxxxxxxxx>

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.
