Subject: [PATCH 4.5 191/238] mmc: sdhci: move initialisation of command error member

4.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Russell King <rmk+kernel@....linux.org.uk>

commit 96776200898cf9c1965b9f8b9a128e94bb6dce18 upstream.

When a command is started, logically it has no error.  Initialise the
command's error member to zero whenever we start a command.
