Subject: net: dsa: mv88e6xxx: Provide dummy implementations for trunk setters
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d38001d30d47051eec265d68378abca7f5109e97;p=linux.git

net: dsa: mv88e6xxx: Provide dummy implementations for trunk setters

Support for Global 2 registers is build-time optional. In the case
where it was not enabled the build would fail as no "dummy"
implementation of these functions was available.

Fixes: 57e661aae6a8 ("net: dsa: mv88e6xxx: Link aggregation support")
