[media] au0828: reset streaming when a new frequency is set
As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.
I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.
Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.
There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.
One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.
This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.
A complete fix, however, would also need to check the PM
conditions for the tuner and demux.
