Staging: hv: warn the world of a bug in the release function
All device release functions need to do something, if not, it's a bug. By merely providing an "empty" release function, it gets the kernel to shut up, but that's not solving the problem at all. Stick a big fat WARN_ON(1); in there to get people's attention. Cc: Hank Janssen <hjanssen@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
