From 7d5789616dd3090fe8486fbb849da3e9d9f36bb9 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 12 Jun 2008 12:13:55 -0700 Subject: [PATCH] pcmcia: simplify rsrc_nonstatic attributes Simplify sysfs attribute registration for sockets without static resource mappings by using an attribute_group. This shrinks object size a bit: use loops in sysfs code, but have more data.
