    mlx4_core: Initialize ctx_list and ctx_lock earlier · b581401e
    Roland Dreier authored
    We may call mlx4_dispatch_event() before mlx4_register_device() is
    called for a device, because for example a catastrophic error happens
    immediately after we enable interrupts.  Therefore priv->ctx_list and
    priv->ctx_lock need to be initialized earlier.
    
    This bug was actually exposed by the MSI-X bug that returned IRQ numbers 
    to drivers in reverse order, so that the first FW command 
    interrupt looked to mlx4 like a catastrophic error.
