From 002dbb2d0d42b4a2c1eef2012c2fe7af48163b3c Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Thu, 8 Dec 2005 23:50:36 +0100 Subject: [PATCH] [PATCH] pcmcia: export stored values in sysfs Export the stored values instead of re-reading everything in the socket information sysfs files, and make them accessible to all users, not only to root.
