[PATCH] IB: fix up major/minor sysfs interface for IB core

Browse source 
Current IB code doesn't work with userspace programs that listen only to
the kernel event netlink socket as it is trying to create its own dev
interface.  This small patch fixes this problem, and removes some
unneeded code as the driver core handles this logic for you
automatically.
