From 2589f1887b0bf9f08ec3d7f3c5705ccb7c628076 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 19 Sep 2006 09:39:19 -0700 Subject: Driver core: add ability for devices to create and remove bin files Makes it easier for devices to create and remove binary attribute files so they don't have to call directly into sysfs. This is needed to help with the conversion from struct class_device to struct device.
