[PATCH net-next] net: dsa: realtek: make interface drivers depend on OF

[Alvin Šipraga]

From: Alvin Šipraga <alsi@bang-olufsen.dk>

The kernel test robot reported build warnings with a randconfig that
built realtek-{smi,mdio} without CONFIG_OF set. Since both interface
drivers are using OF and will not probe without, add the corresponding
dependency to Kconfig.

Hi Alvin

This looks like something which could go into net, not net-next. Could
you add a Fixes: tag.

Otherwise

The driver has been split in net-next and deviates significantly from
what is in net. I can send a patch to net as well, but that will not
cover net-next.

View from net:

    drivers/net/dsa/Kconfig:
    ...
    config NET_DSA_REALTEK_SMI
    ...

View from net-next:

    drivers/net/dsa/Kconfig:
    ...
    source "drivers/net/dsa/realtek/Kconfig"
    ...

    drivers/net/dsa/realtek/Kconfig:
    menuconfig NET_DSA_REALTEK
        ...
    config NET_DSA_REALTEK_MDIO
        ...
    config NET_DSA_REALTEK_SMI
        ...

I am not well-versed in the procedures here, but since 5.17 has now been
released, isn't it more important to fix 5.18, which will soon have the
net-next branch merged in? Hence the patch should target net-next?

As for 5.17 and the old (net) structure, I can send a separate patch to
net. Does that sound OK?

Once that is clarified I can re-send with a Fixes: tag.

Thanks for your help.

Kind regards,
Alvin

Just reply with a Fixes tag, I'll sort it out. I'm about to merge 
the trees so it's a little bit of a special situation.

Thanks Jakub.

Strictly speaking the Fixes: is this:

Fixes: aac94001067d ("net: dsa: realtek: add new mdio interface for drivers")

But the problem existed before that, just in a form unapplicable to
net-next. See my reply to Andrew...

Kind regards,
Alvin

Thanks Alvin for the fix. Maybe you should add both commits.

Woops, you're right. Ought to also carry this tag:

Fixes: 765c39a4fafe ("net: dsa: realtek: convert subdrivers into modules")

Thanks Luiz.
