I guess that's due to INTERCONNECT being a module. There is currently a
discussion about this  with Viresh and Georgi in response to another
automated build failure. Viresh suggests changing CONFIG_INTERCONNECT
from tristate to bool, which seems sensible to me given that interconnect
is a core subsystem.

Let's hold back with this patch/series then until that is sorted out.
