From d9a0157328507c5f563e16a583cd0a063854aebb Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 28 May 2008 09:28:39 -0700 Subject: class: rename "sem" to "class_sem" in internal class structure This renames the struct class "sem" field to be "class_sem" to make things easier when struct bus_type and struct class merge in the future. It also makes grepping for fields easier as well. Based on an idea from Kay.
