[PATCH 16/20] ata: ahci_brcm: Ignore -Woverride-init

From: Lee Jones <hidden>
Date: 2021-01-28 18:11:10
Also in: lkml
Subsystem: libata subsystem (serial and parallel ata drivers), the rest · Maintainers: Damien Le Moal, Niklas Cassel, Linus Torvalds

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):
