[PATCH] drivers/staging/batman-adv: Use (pr|netdev)_<level> macro helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Compile tested only

Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Remove "batman-adv:" from format strings
Use pr_<level>
Use netdev_<level>
