Subject: [PATCH net-next v3 0/9] make drivers/net/ethernet W=1 clean

From: Jesse Brandeburg <jesse.brandeburg@...el.com>

The Goal: move to W=1 being default for drivers/net/ethernet, and
then use automation to catch more code issues (warnings) being
introduced.
The status: Getting much closer but not quite done for all
architectures.

After applying the patches below, the drivers/net/ethernet
directory can be built as modules with W=1 with no warnings (so
far on x64_64 arch only!). As Jakub pointed out, there is much
more work to do to clean up C=1, but that will be another series
of changes.

This series removes 1,247 warnings and hopefully allows the
ethernet directory to move forward from here without more
warnings being added. There is only one objtool warning now.

This version drops one of the Intel patches, as I couldn't
reproduce the original issue to document the warning.

Some of these patches are already sent and tested on Intel Wired
Lan, but the rest of the series titled drivers/net/ethernet
affects other drivers. The changes are all pretty
straightforward.

DaveM: if you want to apply all the intel driver changes
       directly please go ahead.

As part of testing this series I realized that I have ~1,500 more
kdoc warnings to fix due to being in other arch or not compiled
with my x86_64 .config. Feel free to run
$ git ls-files *.[ch] | grep drivers/net/ethernet | xargs scripts/kernel-doc -none
to see the remaining issues.

changes in v3:
	- addressed comments, updated commit messages with
	  warnings noted, updated 9/9 with a few extras that
	  snuck in while I was working, dropped a patch that
	  I couldn't identify the original warning for.
changes in v2:
	- non-rfc
	- addressed list comments from Edward Cree, Jacob Keller and
	  Vinicius Costa Gomes
	- re-split the Intel patches into functional and kdoc only
	- split out the sfc changes that generated discussion to
	  a single patch.


Jesse Brandeburg (9):
  intel-ethernet: clean up W=1 warnings in kdoc
  intel: handle unused assignments
  drivers/net/ethernet: clean up unused assignments
  drivers/net/ethernet: rid ethernet of no-prototype warnings
  drivers/net/ethernet: handle one warning explicitly
  drivers/net/ethernet: add some basic kdoc tags
  drivers/net/ethernet: remove incorrectly formatted doc
  sfc: fix kdoc warning
  drivers/net/ethernet: clean up mis-targeted comments
