From 445aef374594207b278477dfd98fc5d1498d353a Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Mon, 28 Mar 2011 12:46:02 +0000 Subject: [PATCH] acpi: Remove sysfs_create_link from video driver The acpi video driver attempts to explicitly create a sysfs link between the acpi device and the associated PCI device. However, we're now also doing this from the backlight core, which means that we get a backtrace caused by a duplicate file. Remove the code and leave it up to the backlight core.
