[PATCH net-next 00/10] Fix MODULE_DESCRIPTION() for net (p1)

[PATCH net-next 00/10] Fix MODULE_DESCRIPTION() for net (p1)

[Breno Leitao]

There are hundreds of network modules that misses MODULE_DESCRIPTION(),
causing a warnning when compiling with W=1. Example:

	WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/net/arcnet/com90io.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/net/arcnet/arc-rimi.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/net/arcnet/com20020.o


I am working with Jakub to address them, and eventually get a clean W=1
build.

Breno Leitao (10):
  net: fill in MODULE_DESCRIPTION()s for 8390
  net: fill in MODULE_DESCRIPTION()s for SLIP
  net: fill in MODULE_DESCRIPTION()s for HSR
  net: fill in MODULE_DESCRIPTION()s for NFC

  net: fill in MODULE_DESCRIPTION()s for ieee802154

I would write:

    National Semiconductor 8390 Amiga PCMCIA ethernet driver

as this driver does not work on generic platforms with a PCMCIA slot.

If we want to nitpick you could write it as IEEE 802.15.4.

Sure. I will send it soon, since I am splitting the patches in a set of
10. According to the maintainer's request:
https://lore.kernel.org/all/20240122105708.52d33fa0@kernel.org/

For now, I am focusing on Ethernet drivers.

Thanks!

Here is a nitpick as well. The correct acronym [0] is "IPv6 over
Low-Power Wireless Personal Area Network", otherwise it is okay.

Does pcs-lynx.c also have this issue? It can be built at a module.

Absolutely. I can see the warning in pcs-lynx and pcs-pts.

I'm sorry, but net-next is closed for the merge window:

please repost when net-next reopen in ~2 weeks.

As discussed with Paolo offline I'll cherry-pick the patches which
were good from here for net. Because these warnings are generated
at linking time they _all_ pop up on _every_ build our bots do, even
if it's an incremental build touching a tiny corner of the kernel.
