Subject: [PATCH 2/3] ata: pass queued command to ->sff_data_xfer method
Date: Fri, 30 Dec 2016 15:01:17 +0100	[thread overview]
Message-ID: <1483106478-1382-3-git-send-email-b.zolnierkie@samsung.com> (raw)
In-Reply-To: <1483106478-1382-1-git-send-email-b.zolnierkie@samsung.com>

For Atari Falcon PATA support we need to check the current command
in its ->sff_data_xfer method.  Update core code and all users
accordingly.

There should be no functional changes caused by this patch.
