Subject: [PATCH v3 1/4] spi: support spi without dma channel to use can_dma()
Date: Thu, 23 Jul 2015 17:10:40 +0800 [thread overview]
Message-ID: <1437642643-11966-2-git-send-email-leilk.liu@mediatek.com> (raw)
In-Reply-To: <1437642643-11966-1-git-send-email-leilk.liu@mediatek.com>
For spi without dma channel and use can_dma(), it can
use master->dev for struct device.
