-gerrit commit b933096316ccc00d7801f06b0e68604bdfaad002 Author: Stefan Reinauer <[email protected]> Date: Thu Jun 28 12:18:41 2012 -0700 bd82x6x: Support power-on-after-power-fail better Changing CMOS value for power-on-after-power-fail was only honored after reboot, which is counter intuitive (set from "enable" to "disable", power-off, replug device -> device turns on; and similar cases).
