How to revert RFKILL_IOC_NOINPUT ioctl?

[Bastien Nocera <hadess@hadess.net>]

Hey,

I recently implemented support for rfkill multimedia/keyboard keys in
GNOME:
http://www.hadess.net/2016/01/support-for-airplane-mode-keys.html

But, as my laptop doesn't have those keys (or rather it does have them,
but they're not supported by the thinkpad kernel driver), I assigned
the functionality temporarily to other keys. It worked well enough.

I realised looking at the rfkill kernel configuration, and noticed that
it wasn't possible to disable CONFIG_RFKILL_INPUT without enabling the
expert mode. "Why" would be the first question in this mail.

See https://lists.fedoraproject.org/archives/list/kernel@lists.fedoraproject.org/thread/FWCOCU2ODZHK7AQVOWSFJLBXL744LYNO/

To make my GNOME code work, I'd need to disable rfkill-input. But if I
still wanted to allow rfkill-input to work when GNOME isn't running,
such as when switching to a console, or another less-capable desktop
environment. But there doesn't seem to be a counterpart
for RFKILL_IOC_NOINPUT. Any reason why?
