/*
* Note that the cx25840 driver requires that the bridge driver calls the
* v4l2_subdev's load_fw operation in order to load the driver's firmware.
* This will load the firmware on the first invocation (further ones are NOP).
* Without this the audio standard detection will fail and you will
* only get mono.
* Alternatively, you can call the reset operation (this can be done
* multiple times if needed, each invocation will fully reinitialize
* the device).
*
* 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.
