From 7d5a015eece8be9186d3613d595643a520555e33 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Tue, 24 Apr 2007 11:48:20 -0300 Subject: ACPI: thinkpad-acpi: update brightness sysfs interface support Update the brightness sysfs interface (done through the backlight class) to be in line with the rest of the thinkpad-acpi driver. This renames the incorrect, un-obvious, and clash-prone name of "ibm" for the backlight device to a much more fitting and descriptive "thinkpad_screen". This is something I wanted to do for quite a while...
