From 7f548217860a7cf8a345d87792a07512450dfbff Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 2 Nov 2007 15:25:00 -0700 Subject: kobject: convert parisc/pdc_stable to kobj_attr interface This makes the code a bit simpler and and gets us one step closer to deleting the deprecated subsys_attr code. NOTE, this needs the next patch in the series in order to work properly. This will build, but the sysfs files will not properly operate.
