    [PATCH] rt2x00: Fix rfkill handling · 81873e9c

    As reported by Modestas Vainius, enabling rkfill in 1 driver and
    disabling it in a second could cause a NULL pointer exception when
    the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag.
    
    Furthermore, rfkill expects the timeout as a value in milliseconds
    instead of jiffies. Also increase the timeout to a second,
    since this 250ms would be overkill.
    
    Also the flag DEVICE_ENABLED_RADIO_HW is causing problems
    for devices which do not support the hardware button
    while rfkill is enabled in the driver.
    
    To remidy this we should inverse the flag and its meaning,
    rename the flag to DEVICE_DISABLED_RADIO_HW this means that
    by default the radio is enabled by the hardware button (if present)
    and can only be disabled explicitely.
