Not getting into if this patch is correct or not, it's obviously wrong
in that you are adding a new sysfs file to the system, yet you did not
add a Documentation/ABI/ file documenting exactly what this file does
and how to use it.

Please redo it with that added, and fix the obvious typo in the
changelog body as well :)

thanks,
