I can not reproduce it.

I have downloaded net-next and applied the only patch on top.
I have downloaded the above mentioned kernel configuration and
repeated the steps with `make ... oldconfig; make W=1 ...`

Can you shed a light on what's going on here?

Note, the bug is impossibly related to my patch because the new API is in the
same header as already used from the LEDS framework. If it's reproducible, it
should be also without my patch.

If you modify the GitHub link above the 'git remote' command above from
'commit' to 'commits', you can see that your patch was applied on top of
mainline commit 5b7c4cabbb65 ("Merge tag 'net-next-6.3' of
git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next"), which
was before the pull that moved led_init_default_state_get() into
include/linux/leds.h, commit e4bc15889506 ("Merge tag 'leds-next-6.3' of
git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds"). Not sure why
that was the base that was chosen but it explains the error.

Cheers,
Nathan

Because they still haven't moved to using the main branch of netdev
trees, they try to pull master :| I'll email them directly, I think
they don't see the in-reply messages.

Sorry for missing the early information, we didn't notice it and still
apply to the wrong branch. We will resolve this asap to use main branch
instead.

Thanks
