[PATCH 2.6] Add missing MODULE_PARAM to dummy.c (and MAINTAINERShip)

[PATCH 2.6] Add missing MODULE_PARAM to dummy.c (and MAINTAINERShip)

[Jose Luis Domingo Lopez]

Hello:

It seems the "dummy" network interface driver is missing some MODULE_*
macros, needed with kernel 2.6.x and module-init-tools to show
information about the module (parameters, author, description, etc).

A patch follows to (hopefully) correct this. Another patch includes an
entry in the MAINTAINERS file for the "dummy" module. However, I suppose 
the module author (Nick Holloway) will come up and say if he should
still be considered as the module maintainer, so to add the correct
information to the MAINTAINERS file.

Hope the patchs are correct, or at least useful to note the missing bits
I was trying to "patch" and someone else does the "technical" work :-)

Greetings.

this is going backwards.  module_param is the newer (preferred) interface.

I (incorrectly) based my assumptions on the fact that "modinfo dummy"
didn't return any information about the module parameter. I also had a
look at some other modules, like "bonding", "rtl8139", and I assumed
that the MODULE_* macros were the 2.6.x way of doing things.

I was obviously wrong, sorry for the waste of time (anyways, it seems
there are several kernel modules waiting to be updated, maybe I should
give them a look and learn something and try to "fix" them).

Greetings.

It's a mix.  module_param(), MODULE_PARM_DESC(), MODULE_LICENSE(),
MODULE_AUTHOR(), MODULE_DESCRIPTION().

So the whole patch isn't bad, just the bit like:
-module_param()
+MODULE_PARM()

Sure, although some of these changes may not be accepted simply because
they create noise, patch conflicts etc at a time where stability is more
important.  So new code should use the new ones, old code may not all be
converted for some time.

I wouldn't consider myself the maintainer.  I did the original development
to get it into the tree (nearly 10 years ago), but changes have been
made by others.

I don't think an explicit maintainer needs to be mentioned, as it falls
under the umbrella of network maintainance.
