From bb7ca747f8d6243b3943c5b133048652020f4a50 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Tue, 22 Mar 2011 16:30:21 -0700 Subject: backlight: add backlight type There may be multiple ways of controlling the backlight on a given machine. Allow drivers to expose the type of interface they are providing, making it possible for userspace to make appropriate policy decisions.

From a1541710300b083a1a9acff2890d721d15ede62b Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 13 Mar 2011 23:46:22 -0700 Subject: [PATCH] thinkpad-acpi: Some BIOS versions don't end in WW, remove check My X201s BIOS version string is 6QET46V1 (1.16 ). The EC version string is 6QHT28WW-1.09. The driver was requiring that both of these have 'WW' in positions 6 and 7. I don't know what the significance of having 'V1' there instead is, but removing the test makes the driver load on my machine.
