I just made commit: "dvb_usb_v2: rework USB streaming logic" that
breaks that driver PID filter.
it913x driver checks use of PID filter directly from DVB USB v2 core
internal variable "adap->pid_filtering" and stores it to own state.
Calling order of .pid_filter_ctrl() and .pid_filter() was changed
and due to that state was updated too late. Update state earlier.
TODO: checking PID filter usage from DVB USB v2 is not very good idea
as PID filter callbacks are called only when PID filter is enabled.

Control flow order changed a little bit. HW PID filter is now
disabled also when streaming is stopped - earlier it was just
set only when streaming was started.
Control flow is now:
* set streaming status bit
* submit USB streaming packets
* enable HW PID filter
* ask device to start streaming
* N x add PID to device HW PID filter
... streaming video ...
* N x remove PID from device HW PID filter
* ask device to stop streaming
* disable HW PID filter
* kill USB streaming packets
* clear streaming status bit

There was sync mutex which was held over userspace. That is very
wrong and could cause deadlock if different userspace process is
used to "unlock". Wait queue seems to be correct solution for
that kind of synchronizing issue so use it instead.

Commit aab3125c broke em28xx. I traced
this eventually to the change in what algo_data points to. This pointer
is also passed to em28xx_tuner_callback() through several hidden tuner
layers (yuck!) and that callback was not updated.

There's currently a bug on em28xx-i2c that makes it write the
wrong values to register 06, that controlls the I2C bus speed
and bus.

Fix it to change only the I2C bus flag.

It used to be a code that returns arror at ov7660_init.
However, this was removed by changeset c84e412f:

@@ -231,33 +116,40 @@ int ov7660_init(struct sd *sd)
        if (dump_sensor)
                ov7660_dump_registers(sd);

-   err = ov7660_set_gain(&sd->gspca_dev, sensor_settings[GAIN_IDX]);
-   if (err < 0)

-   err = ov7660_set_auto_white_balance(&sd->gspca_dev,
-           sensor_settings[AUTO_WHITE_BALANCE_IDX]);
-   if (err < 0)
-           return err;

As complained by gcc:
	drivers/media/usb/gspca/m5602/m5602_ov7660.c: In function 'ov7660_init':
	drivers/media/usb/gspca/m5602/m5602_ov7660.c:99:9: warning: variable 'err' set but not used [-Wunused-but-set-variable]

It should be noticed that the original error code was crappy, as it wasn't
returning any error if sensor init fails.

Fix it by returning an error if the sensor can't be initialized.

Changeset 8f3741e0 accidentally broke the CNR estimation. It should
be calculated as "a + b - c". However, previously, the subtraction
by c only occurred if SNR would be positive, due to a bad binding
to DVBv3 API.

This also fixes the following warning:
