Subject[PATCH] staging: gdm724x: Update logging
From
Date
Make the logging prefixes match the module names
by adding #define pr_fmt(fmt) KBUILD_MODNAME and
converting printks to netdev_<level> when a
struct netdevice * is available and and pr_<level>
when not.

Remove embedded prefixes.
Add missing terminating newlines.
Remove an unnecessary rx-dropped message.
Remove an unnecessary temporary variable.
