  24 /* Note that the cx25840 driver requires that the bridge driver calls the
  25    v4l2_subdev's init operation in order to load the driver's firmware.
  26    Without this the audio standard detection will fail and you will
  27    only get mono.
  28
  29    Since loading the firmware is often problematic when the driver is
  30    compiled into the kernel I recommend postponing calling this function
  31    until the first open of the video device. Another reason for
  32    postponing it is that loading this firmware takes a long time (seconds)
  33    due to the slow i2c bus speed. So it will speed up the boot process if
  34    you can avoid loading the fw as long as the video device isn't used. */
