From 79b3891587741dfac72cdfead1f2764b56a567b0 Mon Sep 17 00:00:00 2001 From: "David S. Miller" <davem@davemloft.net> Date: Mon, 6 Jun 2011 17:00:35 -0700 Subject: [PATCH] irda: iriap: Use seperate lockdep class for irias_objects->hb_spinlock The SEQ output functions grab the obj->attrib->hb_spinlock lock of sub-objects found in the hash traversal. These locks are in a different realm than the one used for the irias_objects hash table itself. So put the latter into it's own lockdep class.
