    rfkill: rename the rfkill_state states and add block-locked state · 5005657c
    Henrique de Moraes Holschuh authored
    The current naming of rfkill_state causes a lot of confusion: not only the
    "kill" in rfkill suggests negative logic, but also the fact that rfkill cannot
    turn anything on (it can just force something off or stop forcing something
    off) is often forgotten.
    
    Rename RFKILL_STATE_OFF to RFKILL_STATE_SOFT_BLOCKED (transmitter is blocked
    and will not operate; state can be changed by a toggle_radio request), and
    RFKILL_STATE_ON to RFKILL_STATE_UNBLOCKED (transmitter is not blocked, and may
    operate).
    
    Also, add a new third state, RFKILL_STATE_HARD_BLOCKED (transmitter is blocked
    and will not operate; state cannot be changed through a toggle_radio request),
    which is used by drivers to indicate a wireless transmiter was blocked by a
    hardware rfkill line that accepts no overrides.
    
    Keep the old names as #defines, but document them as deprecated.  This way,
    drivers can be converted to the new names *and* verified to actually use rfkill
    correctly one by one.
