[PATCH 2/2] cciss: fix flush cache transfer length

From: Stephen M. Cameron
Date: Mon Nov 28 2011 - 11:15:05 EST


From: Stephen M. Cameron <scameron@xxxxxxxxxxxxxxxxxx>

We weren't filling in the transfer length of the
flush cache command (it transfers 4 bytes of zeroes).
Firmware didn't seem to be bothered by this, but it
should be fixed.
