[PATCH] pull in necessary header files for cdev.h

linux/cdev.h uses struct kobject and other structs and should therefore
include them.  Currently, a module either needs to add the missing includes
itself, or, in case a module includes other headers already, needs to put
<linux/cdev.h> last, which goes against a alphabetically-sorted include
list.
