Hello Ike,
i'm back at this problem.
I have loaded module ideapad_laptop with modification as above.
On triggering the hardware wifi button on->off->on i get the following
messages:
[ 730.712030] usb 3-5: USB disconnect, device number 4
[ 730.713156] btusb_bulk_complete: hci0 urb ffff8801178d7b40 failed to

[ 732.008870] notified. event: 0x80.
[ 732.650384] usb 3-5: new full speed USB device number 5 using ohci_hcd
Other function buttons (e.g. screen brightness adjustment) also produce
messages as above "notified. event: 0x80."
