From f5ef9d11fd255b30b455d18f8d721bc44cd1296b Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 27 Oct 2006 01:03:31 -0700 Subject: [SPARC]: Fix bus_id[] string overflow. dp->path_component_name can be larger than ->bus_id[] so use a different naming scheme for this stuff. Noticed by Jurij Smakov. Signed-off-by: David S.
