Subject[PATCH 16/20] ata: ahci_brcm: 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):
