libie: fix linking with libie_{adminq,fwlog} when CONFIG_LIBIE=n

[PATCH net-next] libie: fix linking with libie_{adminq,fwlog} when CONFIG_LIBIE=n

Posted by Alexander Lobakin 2 weeks, 1 day ago

Initially, libie contained only 1 module and I assumed that new modules
in its folder would depend on it.
However, Michał did a good job and libie_{adminq,fwlog} are completely
independent, but libie/ is still traversed by Kbuild only under
CONFIG_LIBIE != n.
This results in undefined references with certain kernel configs.

Tell Kbuild to always descend to libie/ to be able to build each module
regardless of whether the basic one is enabled.
If none of CONFIG_LIBIE* is set, Kbuild will just create an empty
built-in.a there with no side effects.

Fixes: 641585bc978e ("ixgbe: fwlog support for e610")

Sending directly to net-next to quickly unbreak net-next and
linux-next builds.
Also to net-next as the blamed commit landed recently and is
not present in any other tree.
