[PATCH] staging: mt7621-eth: Fix sparse warning in ethtool.c

[PATCH] staging: mt7621-eth: Fix sparse warning in ethtool.c

[Chris Coffey]

Include the local ethtool.h header file in mtk_eth_soc.h so
implementation files have centralized access to it.

This fixes the following sparse warning:

drivers/staging/mt7621-eth/ethtool.c:213:6: warning: symbol
'mtk_set_ethtool_ops' was not declared. Should it be static?

How about just moving ethtool.h above the mtk_eth_soc.h include?

Putting .h file dependancies in other .h files is generally not a good
idea if at all possible.  Keeping them "clean" is better, and this
driver has a bunch of work to go there, so let's not make it worse :)

[PATCH v2] staging: mt7621-eth: Fix sparse warning in ethtool.c

[Chris Coffey]

This fixes the following sparse warning:

drivers/staging/mt7621-eth/ethtool.c:213:6: warning: symbol

Changes in v2:
 - Per GregKH's feedback (thanks!), don't add unnecessary new .h file
 dependencies. This patch version reverts those changes and fixes the
 problem directly in ethtool.c (which is that it didn't include
 ethtool.h anywhere -- mtk_set_ethtool_ops is not static).

Hi, Neil

Forgive me I cannot find the cover letter in the original series in my
mailbox to make a reply, so I rudely made here just letting you know
something good to the growth of mt7621 support in upstream.

do you have maintained an out-of-tree branch to boot the mt7621 machine
with those staging patches?

If so, it would become a bit easier for me that maybe I could give a
hand for migrating these staging driver for mt7621 to mainline. I
thought mmc, pci, ethernet, gsw and hsdma all could probably reuse the
current mainline code.

I can boot v4.16 plus staging-next on my mt7621 with no other patches.
An important fix (a63d706ea71919) landed in 4.16-rc7.

It do have
  https://github.com/neilbrown/linux/commits/gnubee/v4.15

which was part of preparation for this, but now that very nearly all I
need is in mainline or on its way, I won't be doing much more in that
tree.

I agree that it is quite likely that several of these drivers could and
should reuse current mainline code.  I would love to have some help
sorting this out.  I won't have much time myself to dig into it for
several weeks, but I'll make time to review and test any code that is
contributed.

Hi,

I have started a patch series for the mmc driver that is currently in
staging, that makes some of the first cleanups (whitespace, indent,..)
and also starts to clean up the code, to make the similarities and
differences to the current mainline code clearer. The series is far
from being complete, but I think I'm going to send it out today, so
you can look and comment.

I would suggest that we continue cleaning the code that is currently
in staging to remove the dead parts and make the diff to the mainline
code obvious. Do you agree with that proposal or do you suggest a
different plan?

Christian

I think this is an excellent plan - thanks for doing it.
I'll hopefully look over your patches today and send any comments.

Thanks,
