Bug#752864: broadcom-sta-dkms: External module driver does not compile on a Linux 3.15.x kernel

[Michele Porelli]

I backported ubuntu patch (
http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/utopic/bcmwl/utopic/view/head:/debian/patches/0012-add-support-for-Linux-3.15.patch
)


It works for me.
