From bcc3e1726d827c2d6f62f0e0e7bbc99eed7ad925 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Tue, 14 Jan 2014 21:24:21 +0100 Subject: [PATCH] mmc: block: Use R1 responses for stop cmds for read requests While using open ended transmission and thus ending the transfer by sending a stop command, we shall use R1B only for writes and R1 shall be used for reads. Previously R1B were used in both cases.
