3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
commit 4b200b4604bec3388426159f1656109d19fadf6e upstream.
This fixes a several year old regression that I found while trying
to get the Yoga 3 11 to work. The ideapad_rfk_set function is meant
to send a command to the embedded controller through ACPI, but
as of c1f73658ed, it sends the index of the rfkill device instead
of the command, and ignores the opcode field.
This changes it back to the original behavior, which indeed
flips the rfkill state as seen in the debugfs interface.
