Subject: [PATCH 3.9-stable] s5p makefiles: don't override other selections on
 obj-[ym]

This patch looks like it should be in the 3.9-stable tree, should we apply
it?

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

From: "Mauro Carvalho Chehab <mchehab@...hat.com>"

commit 5f63adbb4cb9f952a8daee97f89c8811da5fd68a upstream

The $obj-m/$obj-y vars should be adding new modules to build, not
overriding it. So, it should never use
	$obj-y := foo.o
instead, it should use:
	$obj-y += foo.o

Failing to do that is very bad, as it will suppress needed modules.
