Please fix whatever script you're using to generate your mails, it's
generating corrupt headers.  Please also use subject lines consistent
with the rest of the subsystem - between the two I very nearly just

Like I said to Paul this isn't fixing the actual issue - think about why
the symbol was there in the first place and why it was removed.  There
is a problem here but this would make it less likely that it would be
properly fixed.

I think Richard's mail didn't end up on lkml. But it's pretty clear what
it must have looked like.

Would you mind going through this one step at a time, just to make sure
_I_ understand what it is that you'd like to see?

If so, to be absolutely sure we start from the same point: do you agree
that the above line now effectively reads
    depends on SND_SOC_SAMSUNG && (MACH_SMDK6410 || MACH_SMDKC100 || MACH_SMDKV210 || MACH_SMDKC110 || false || false)

because there's neither a Kconfig symbol MACH_SMDKV310 nor a Kconfig
symbol MACH_SMDKC210?

I can see what it looked like from my inbox, but my mail client can't
understand them at all and hence didn't think the mails were sent to me
and just ignored them when hitting reply.

Yes, that's correct.  Now, like I say think about what the symbol was
there for in the first place.

So, next step: the Kconfig symbols MACH_SMDKV310 and MACH_SMDKC210 were
removed in commit 383ffda2fa ("ARM: EXYNOS: no more support non-DT for
EXYNOS SoCs"). That commit was part of v3.11. Correct?

Thanks for your patience.

Indeed, so we can see that these platforms were converted to use DT and
the symbols were removed as a result.  This means that a good fix here
is to ensure that the driver can be used with DT platforms.

One of the problems I face is that I find it hard to understand how this
stuff works in v3.10 (ie, before MACH_SMDKV310 and MACH_SMDKC210 were
dropped).

See, if you scan v3.10:arch/arm/mach-exynos/mach-smdkv310.c you'll
notice the string "smdk-audio". If you grep that string you get a few
hits. But none in v3.10:sound/soc/samsung/smdk_wm9713.c. And if you scan
v3.10:sound/soc/samsung/smdk_wm9713.c for strings you'll find stuff like
"wm9713-hifi",  "wm9713-codec", and "soc-audio". But these don't show up
in v3.10:arch/arm/mach-exynos/mach-smdkv310.c. So it's not obvious how
these two files relate.

And I'm left wondering why SND_SOC_SAMSUNG_SMDK_WM9713 actually depends
on (among other symbols) MACH_SMDKV310 and MACH_SMDKC210 in v3.10.

The hardware is physically present on those boards but must be selected
with DIP switches, the device registration needs to be changed in the
kernel when that happens (as the DT must be when it is in use).

I found same patch ([PATCH] ARM: s3c24xx: get rid of unneeded selects)

In v3.14-rc4 these two symbols suddenly got removed, see commit
eaff64705dd5 ("ASoC: samsung: Remove invalid dependencies"). It does
exactly what I proposed last year, see
https://lkml.org/lkml/2013/7/14/27 . (That link currently shows a rather
empty page; is lkml.org having problems again?)

That commit is fine with me, of course. I now see no reason to continue
my, rather slowly progressing, search for the problem that you wanted to
get properly fixed. I suppose another commit already fixed it.

No, but it's someone from Samsung (Sachin works with the Samsung landing
team at Linaro) not caring about those drivers on these boards any more
and mentioning the DT conversion which is rather different to someone
doing mechanical cleanup with no mention of where the symbols went.

It should be fairly obvious that if the reason symbols are being removed
due to DT conversion of the platforms then the default thing should be
that the drivers be being converted to DT and appropriate DT entries
being added to the board DTS files, but more generally the important
thing is that some understanding is shown as to why the symbols vanished
and why the mechanical fix suggested is OK.

It's not clear to me whether an actual decision was eventually made.
