Subject: Enable MSI if the node contains an msi-map, like we already do in pciecam(4).
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=d0adc91200b87d651e2dcaf378e06e37972febc7;p=openbsd

Enable MSI if the node contains an msi-map, like we already do in pciecam(4).
This will make MSIs work on the Lenovo x13s as soon as an updated device tree
is installed.
