    Subject[PATCH v2 RESEND 09/23] hpsa: Fallback to MSI rather than to INTx if MSI-X failed
    Date
    Currently the driver falls back to INTx mode when MSI-X
    initialization failed. This is a suboptimal behaviour
    for chips that also support MSI. This update changes that
    behaviour and falls back to MSI mode in case MSI-X mode
    initialization failed.
