This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Remove from include/linux/netdevice.h helpers
that send debug/info/warnings to syslog.
We plan adding more helpers in following patches.
v2: added two includes, and 'struct net_device' forward declaration
to avoid compile errors (kernel bots)
