Subject: [PATCH V6 08/12] mmc: block: Use local variables in mmc_blk_data_prep()
Date: Fri, 25 Aug 2017 15:43:51 +0300	[thread overview]
Message-ID: <1503665035-16231-9-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1503665035-16231-1-git-send-email-adrian.hunter@intel.com>

Use local variables in mmc_blk_data_prep() in preparation for adding CQE
support which doesn't use the output variables.
