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

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

From: Luis de Bethencourt <luisbg@osg.samsung.com>

commit ef3149eb3ddb7f9125e11c90f8330e371b55cffd upstream.

sca3000_read_ctrl_reg() returns a negative number on failure, check for
this instead of zero.
