Subject: [PATCH RFC 2/2] drivers/ata: convert pata_falcon to arch platform device
Date: Fri, 21 Jun 2019 08:47:22 +1200 [thread overview]
Message-ID: <1561063642-13900-3-git-send-email-schmitzmic@gmail.com> (raw)
In-Reply-To: <CAMuHMdUcUqWWGNngNV3EpEq5wSsf5qTVeZvTB9gX1e26Jrq1xA@mail.gmail.com>
The Atari platform device setup now provides a platform device
for the Falcon IDE interface. Use this in place of the simple platform
device set up in the old pata_falcon probe code.
