The Comedi "comedi_isadma.h" header is included by the source for the "comedi_isadma" helper module and other modules that use it. It does not compile cleanly when it is the first header file included. It uses the `dma_addr_t` type, so include <linux/types.h> to declare it. (Also, that indirectly takes care of the use of `NULL`.) It uses `struct comedi_device *` in various function prototypes, so add an incomplete declaration of `struct comedi_device`.
