    net: ipa: do not cache channel state · a2003b30
    Alex Elder authored
    It is possible for a GSI channel's state to be changed as a result
    of an action by a different execution environment.  Specifically,
    the modem is able to issue a GSI generic command that causes a state
    change on a GSI channel associated with the AP.
    
    A channel's state only needs to be known when a channel is allocated
    or deallocaed, started or stopped, or reset.  So there is little
    value in caching the state anyway.
    
    Stop recording a copy of the channel's last known state, and instead
    fetch the true state from hardware whenever it's needed.  In such
    cases, *do* record the state in a local variable, in case an error
    message reports it (so the value reported is the value seen).
