Sorry for the 9533b292a7ac problem.
At this point the in release cycle, I think Arnd's revert is best.
If there is interest, I've put a little thought into an alternative fix:
making INFINIBAND_ADDR_TRANS tristate. But it's nontrivial.
So I prefer this simple revert for now.
Is that a normal thing to do?
For me: no, it's not normal. In my use case I merely want to disable
INFINIBAND_ADDR_TRANS while continuing to use INFINIBAND. This is
supported with f7cb7b85be55 ("IB: make INFINIBAND_ADDR_TRANS
configurable").
During f7cb7b85be55 development https://lkml.org/lkml/2018/4/30/1073
suggested that we drop dependency on both INFINIBAND and
INFINIBAND_ADDR_TRANS. Thus 9533b292a7ac ("IB: remove redundant
INFINIBAND kconfig dependencies").
But 9533b292a7ac led to the randconfig build errors reported and thus
("IB: Revert "remove redundant INFINIBAND kconfig dependencies"").
So I see no need to do anything more than apply ("IB: Revert "remove
redundant INFINIBAND kconfig dependencies"").
Doug: do you need anything from me on this?
I can take the revert..
Jason
Thanks.

[PATCH] IB: Revert "remove redundant INFINIBAND kconfig dependencies"
Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends
on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a
link error when another driver using it is built-in. The
INFINIBAND_ADDR_TRANS dependency is insufficient here as this is
a 'bool' symbol that does not force anything to be a module in turn.
