From 689bf406829c8a5e44ebf8fc8918b77b3806ee48 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 1 Sep 2009 20:12:58 -0700 Subject: [PATCH] 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.
