Subject: [PATCH 09/20] ata: acard-ahci: Ignore -Woverride-init
Date: Thu, 28 Jan 2021 18:02:28 +0000	[thread overview]
Message-ID: <20210128180239.548512-10-lee.jones@linaro.org> (raw)
In-Reply-To: <20210128180239.548512-1-lee.jones@linaro.org>

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):
