Fix several drivers/media/pci/ddbridge/ddbridge-core.c: warning: symbol ... was not declared. Should it be static? drivers/media/pci/ddbridge/ddbridge-core.c: warning: Using plain integer as NULL pointer drivers/media/pci/ddbridge/ddbridge-io.h: warning: cast removes address space of expression drivers/media/pci/ddbridge/ddbridge-io.h: warning: incorrect type in argument 1 (different address spaces) at multiple places.
