Subject: [PATCH V5 09/13] mmc: block: Use local variables in mmc_blk_data_prep()
Date: Thu, 10 Aug 2017 15:08:14 +0300	[thread overview]
Message-ID: <1502366898-23691-10-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1502366898-23691-1-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.
