Subject: [PATCH 11/15] sfc: don't call dma_supported
Date: Sat,  3 Oct 2015 17:19:35 +0200	[thread overview]
Message-ID: <1443885579-7094-12-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1443885579-7094-1-git-send-email-hch@lst.de>

dma_set_mask already checks for a supported DMA mask before updating it,
the call to dma_supported is redundant.
