    Subject[PATCH 15/20] ata: sata_highbank: Ignore -Woverride-init
    Date
    Some ATA drivers use the SCSI host template, a series of interwoven
    macros, to aid with initialisation. Some of these macros conflict,
    resulting in the over-writing of previously set values.

    This is known behaviour and can be safely ignored.

    Fixes the following W=1 kernel build warning(s):
