Re: [Buildroot] [RESEND v3 1/1] support: kconfig: Fix compiler warnings

[Petr Vorel <petr.vorel@gmail.com>]

Hi all,

[ Cc Edgar and Arnout involved in 324612d68e and Titouan working on kconfig
update ]

@Kanak I'm sorry, reading the description of the failure:
324612d68e ("support/kconfig: fix compiler warnings")

    Normally, we want changes to kconfig to be reflected by patches in
    support/kconfig/patches. This makes it easier to resync with upstream
    kconfig. However, in this case, everything that is changed here is
    already changed completely (and differently) upstream, so there is no
    added value in keeping the patch.

That means I was wrong in v1 where I asked for creating a patch.
OTOH it's a bit confusing, it should be at least documented in
support/kconfig/README.buildroot.

Thanks, for pointing this out. Indeed it is. I'm sorry that I haven't finished
the review. Unfortunately nobody else haven't reviewed it [4] [5] (state new in
patchwork for one year old patch is not good).

Thanks for the reminder. I'd actually prefer to have this update. There is some
requirement to change it but that should be trivial to fix in new version.
@Titouan do you plan to send a new version?

Kind regards,
Petr
