From: Aaron Lu <[email protected]> 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.
