I think it's higher in the dependency tree than that.

They must go together ... right.  Anything using gpiolib
without the interface it implements needs a head-exam. ;)

But since ISTR that Kconfig (still) doesn't get dependencies
right when you "select" something that depends on something
else, that particular solution won't fly.

No; GENERIC_GPIO is the interface, HAVE_GPIO_LIB is one
of the valid ways to implement it.

It should work if HAVE_GPIO_LIB selected GENERIC_GPIO...
