Nobody but me. Therefore it get's a NACK.

Indeed the banners are pretty broken now ...

Before:

can: controller area network core (rev 20090105 abi 8)
NET: Registered protocol family 29
can: raw protocol (rev 20090105)
can: netlink gateway (rev 20101209)
can: broadcast manager protocol (rev 20090105 t)

After Joe's patch:

can: controller area network core (rev 20090105 abi 8)
NET: Registered protocol family 29
can_raw: raw protocol (rev 20090105)
can_gw: netlink gateway (rev 20101209)
can_bcm: broadcast manager protocol (rev 20090105 t)

IMO if you want to use pr_fmt() it should at least look like this:

can: controller area network core (rev 20090105 abi 8)
NET: Registered protocol family 29
can_raw: can raw protocol (rev 20090105)
can_gw: can netlink gateway (rev 20101209)
can_bcm: can broadcast manager protocol (rev 20090105 t)

I'm fine with using pr_fmt() for error/warning output but not for the banner
in the currently suggested way.

Regards,
Oliver
