From 85cc1c33196abd0640e0195389c6683661afb83c Mon Sep 17 00:00:00 2001 From: Corneliu Doban Date: Mon, 9 Feb 2015 16:06:29 -0800 Subject: [PATCH] mmc: sdhci: do not set AUTO_CMD12 for multi-block CMD53 For CMD53 in block mode, the host does not need to stop the transfer, as it stops when the block count (present in CMD53) is reached.
