Hi Matthew,
I reverted 997daa1bd9aca412ab97955a35b26c460c0ec7a4 and add a check in
hp_wmi_rfkill_setup as below:

It actually works better than 997daa1bd9aca412ab97955a35b26c460c0ec7a4
on new systems, but I don't have old hp systems for testing good HP
WMI 0x05 Set command.
Any suggestions are appreciated.
