Subject: [PATCH] media: ddbridge: fix build warnings

From: Randy Dunlap <rdunlap@...radead.org>

Fix 2 build warnings.
These functions are void, so drop the "return"s.

./drivers/media/pci/ddbridge/ddbridge-io.h: warning: 'return' with a value, in function returning void [enabled by default]:  => 50:2, 55:2
