Subject: [PATCH v1 3/3] spi: topcliff-pch: use pci_get_dma_device() helper
Date: Fri, 25 Jul 2014 16:31:44 +0300	[thread overview]
Message-ID: <1406295104-20082-3-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1406295104-20082-1-git-send-email-andriy.shevchenko@linux.intel.com>

Since we have pci_get_dma_device() public we may use it in the drivers. It
considers the function 0 as a DMA controller.
