+/* Note that the cx25840 driver requires that the bridge driver calls the
+   v4l2_subdev's init operation in order to load the driver's firmware.
+   Without this the audio standard detection will fail and you will
+   only get mono.
+
+   Since loading the firmware is often problematic when the driver is
+   compiled into the kernel I recommend postponing calling this function
+   until the first open of the video device. Another reason for
+   postponing it is that loading this firmware takes a long time (seconds)
+   due to the slow i2c bus speed. So it will speed up the boot process if
+   you can avoid loading the fw as long as the video device isn't used. */
