From: Aaron Lu <aaron...@intel.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.
