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

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

From: Mauro Carvalho Chehab <mche...@osg.samsung.com>

commit 12f4543f5d6811f864e6c4952eb27253c7466c02 upstream.

The maximum size for a DiSEqC command is 6, according to the
userspace API. However, the code allows to write up to 7 values:
        drivers/media/dvb-frontends/s5h1420.c:193 s5h1420_send_master_cmd() 
error: buffer overflow 'cmd->msg' 6 <= 7
