    ath10k: specifically mark a debug workaround for an early firmware crash
    
    During the last import a (debug) workaround to avoid an early firmware
    crash was imported.  In order to remember and to separate it from
    upstream sources put it under #ifdef
    
    MFC after:      20 days
