    iwlwifi: pcie: fix tracking of cmd_in_flight · fc8a350d
    Ilan Peer authored
    The cmd_in_flight tracking was introduced to workaround faulty
    power management hardware, by having the driver keep the NIC
    awake as long as there are commands in flight. However, some of
    the code handling this workaround was unconditionally executed,
    which resulted with an inconsistent state where the driver assumed
    that the NIC was awake although it wasn't.
    
    Fix this by renaming 'cmd_in_flight' to 'cmd_hold_nic_awake' and
    handling the NIC requested awake state only for hardwares for
    which the workaround is needed.
