commit 7a36b06d61c8951cb1a9866c7b6ae2176ca25d3b Author: Vladimir Serbinenko phcoder@gmail.com Date: Wed May 13 18:22:49 2015 +0200
lenovo: Disable radio when suspending or turning off.
Without this some radios may remain operational. The may consume power but the immediate demonstrable effect is wireless LED still being on. Coreboot will reenable radios on resume or poweron.
