[PATCH] b43/b43legacy: add RFKILL_STATE_HARD_BLOCKED support

[PATCH] b43/b43legacy: add RFKILL_STATE_HARD_BLOCKED support

[drago01]

Hi,

The attached  patch adds RFKILL_STATE_HARD_BLOCKED to the b43/b43legacy drivers.
Note: I don't have any hardware to test on, so if you have the
hardware please test.

-----------

This patch sets the rfkill state to RFKILL_STATE_HARD_BLOCKED when the
radio is killed
by the hardware switch.

While at it, if b43 still has any input layer stuff, especially any input
polldev stuff, please rip that off.

Userspace or a platform driver should listen to the b43 reports on the
rfkill notifier chain (or uevents) and issue the input events.

In b43legacy the structure name is 'b43legacy_rfkill'.  Please make
sure you compile patches before submitting them.
