Wysocki" <rafael.j.wysocki@...el.com>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 010/146] ACPI / video: Fix initial level validity test From: Aaron Lu <aaron.lu@...el.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 9efa5e50598c5568b0678bb411b239a0b6e9a328 upstream. When testing if the firmware's initial value is valid, we should use the corrected level value instead of the raw value returned from firmware.
