You can't. The type is not a bitfield:
------------< snip <------< snip <------< snip <------------
struct v4l2_capability
{
char name[32]; /* Descriptive, and unique */
int type; /* Device type, see below */
int inputs; /* Num video inputs */
int outputs; /* Num video outputs */
int audios; /* Num audio devices */
int maxwidth;
int maxheight;
int minwidth;
int minheight;
int maxframerate;
__u32 flags; /* Feature flags, see below */
__u32 reserved[4];
};
/* Values for 'type' field */
#define V4L2_TYPE_CAPTURE 0 /* Is a video capture device */
#define V4L2_TYPE_CODEC 1 /* Is a CODEC device */
#define V4L2_TYPE_OUTPUT 2 /* Is a video output device */
#define V4L2_TYPE_FX 3 /* Is a video effects device */
#define V4L2_TYPE_VBI 4 /* Is a VBI capture device */
#define V4L2_TYPE_VTR 5 /* Is a tape recorder controller */
#define V4L2_TYPE_VTX 6 /* Is a teletext device */
#define V4L2_TYPE_RADIO 7 /* Is a radio device */
#define V4L2_TYPE_VBI_INPUT 4 /* Is a VBI capture device */
#define V4L2_TYPE_VBI_OUTPUT 9 /* Is a VBI output device */
#define V4L2_TYPE_PRIVATE 1000 /* Start of driver private types */
