The ARCH_WANT_OPTIONAL_GPIOLIB symbol was removed in commit 65053e1a7743
("gpio: delete ARCH_[WANTS_OPTIONAL|REQUIRE]_GPIOLIB"). GPIOLIB should
just be selected explicitly if needed.

Remove the ARCH_WANT_OPTIONAL_GPIOLIB select from RISCV.

See commit 0145071b3314 ("x86: Do away with
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB") and commit da9a1c6767 ("arm64: do
away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB") as well.

Discovered with the
https://github.com/ulfalizer/Kconfiglib/blob/master/examples/list_undefined.py
script.

There's also a select of a globally undefined symbol RISCV_IRQ_INTC
here. I couldn't dig up any historical or unmerged definition for it
either. Googling just gets you the select.

Cheers,

This should probaly be replaced with
select GPIOLIB

That'd make more sense if GPIOLIB is actually used. The select has
been a no-op since mid-2016 at least, but maybe something else selects
GPIOLIB.

Just replace it with your own patch once you've figured out the proper
fix. More efficient than having a middle man making (sometimes poor)
guesses.

I think it's just a side effect of the new RISCV arch being developed
outside of the mainline kernel. And they may have had a gpio driver
outside of the mainline as well.

Normally we don't encourage out-of-tree development, but new archs
are a bit of an exception since they have to be merged as a big
piece of upfront code at some point...

Anyways, if they don't have any GPIO in their machine yet, let's
let the RISCV maintainers apply this.

Yours,
Linus Walleij

It looks like this slipped through, the symbol has been renamed RISCV_INTC.  A 
patch to remove it is
