This is a check designed to make sure that what we specify in the Fedora
configurations match what is generated via Kconfig. The output
is stating that the Fedora tree has (e.g.) CONFIG_HID=m set but when
run against the kernel configuration generation it comes out as
# CONFIG_HID is not set. The easiest way to fix this is to make
all those options match whatever is being generated (so mark all
those options not set)

This is saying that CONFIG_RESET_CONTROLLER isn't specified
as a Kconfig value for s390x. You need to explicitly set it.
