Hmmm... you are right (here and in other patches) but why am I getting
all these errors:

has unmet direct dependencies (HAS_IOMEM)
?
(ARCH=um, allyesconfig)

The problem is that Kconfig will just print any option that
selects the one that has a missing dependency, but doesn't
show which of those are actually enabled.

Indeed... but apparently putting direct HAS_IOMEM dependency on these
symbols silences the Kconfig warning.

Adding depends here (and in other places) really helps... but it
should not have any impact...

I think patch 5 by itself would have been sufficient.

Thanks for analysis. Since all patches are independent (and IMHO the
last one is not needed really) so I won't resend the patchset. Instead
let maintainer pick what is meaningful.

Best regards,
