Subject: [PATCH 13/17] mmc: sdhci: pass the cookie into sdhci_pre_dma_transfer()
Date: Sat, 19 Dec 2015 20:31:10 +0000	[thread overview]
Message-ID: <E1aAO9m-0007zI-IW@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20151219202851.GS8644@n2100.arm.linux.org.uk>

Pass the desired cookie for a successful map.  This is in preparation to
clean up the MAPPED/GIVEN states.
