    powerpc/eeh: Avoid misleading message "EEH: no capable adapters found" · ee8c446f
    Mauro S. M. Rodrigues authored
    Due to recent refactoring in EEH in:
    commit b9fde58d ("powerpc/powernv: Rework EEH initialization on
    powernv")
    a misleading message was seen in the kernel message buffer:
    
    [    0.108431] EEH: PowerNV platform initialized
    [    0.589979] EEH: No capable adapters found
    
    This happened due to the removal of the initialization delay for powernv
    platform.
    
    Even though the EEH infrastructure for the devices is eventually
    initialized and still works just fine the eeh device probe step is
    postponed in order to assure the PEs are created. Later
    pnv_eeh_post_init does the probe devices job but at that point the
    message was already shown right after eeh_init flow.
    
    This patch introduces a new flag EEH_POSTPONED_PROBE to represent that
    temporary state and avoid the message mentioned above and showing the
    follow one instead:
    
    [    0.107724] EEH: PowerNV platform initialized
    [    4.844825] EEH: PCI Enhanced I/O Error Handling Enabled
