Staging: add the go7007 video driver
Todo: - checkpatch.pl cleanups - sparse cleanups - lots of little modules, should be merged together and added to the build. - testing? - handle churn in v4l layer. Many thanks to Ross Cohen <rcohen@snurgle.org> for cleanup patches on this driver. Cc: Ross Cohen <rcohen@snurgle.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

+ * detect_client function (the one that's normally passed to i2c_probe).
+ *
+ * When a new go7007 device is connected, we can look up in a board info

+ * which I2C client module to load. The client driver module will register
+ * itself here, and then we can call the registered detect_client function
+ * to force-load a new client at the address listed in the board info table.
+ *
+ * Really the I2C subsystem should have a way to force-load I2C client
+ * drivers when we have a priori knowledge of what's on the bus, especially
+ * since the existing I2C auto-probe mechanism is so hokey, but we'll use
+ * our own mechanism for the time being. */
