The bridge takes some time to update after a write, so apps doing a quick
write/read can get the old value back.

Currently the spca501 driver only works the first time used, then the cam needs
to be unplugged or the driver reloaded, this is because currently the data
which should be send each time the stream is started is send only once.
Likewise currently the data to initialize the cam is send from the probe
function, and thus will not get send after a suspend/resume.
This patch fixes this by sending both at the right time.
