[media] v4l2-dv-timings: fix CVT calculation
This patch fixes two errors that caused incorrect format detections:
The first bug is in the calculation of the vertical backporch: the combined
period of vsync and backporch must *exceed* a certain minimum value, and not
be equal to it.
The second bug is a rounding error in the reduced blanking calculation:
expand the ideal_duty_cylce to be in parts per ten thousand to avoid
rounding errors.

When streamoff is called on the context and the context
is added to the job_queue,
1] sometimes device_run receives the empty vb2 buffers (as
v4l2_m2m_streamoff is dropping the ready queue).
2] sometimes v4l2_m2m_job_finish may not succeed as the m2m_dev->curr_ctx
is made NULL in the v4l2_m2m_streamoff()
The above points may stop the execution of the other queued contexts.
This patch makes sure that before streamoff is executed on any context,
that context should "not be running" or "not queued" in the job_queue.
1] If the current context is running, then abort job will be called.
2] If the current context is queued, then the context will be removed from

fix the issue caused by the set_frontend bad hook, and add the

When the frontend drivers got converted to DVBv5 API, the original
hook that tracked when a frontend is set got removed, being replaced
by an approach that would use the gate control. That doesn't work
fine with some boards. Also, the code were called more times than
desired.
Replace it by a logic that will hook the dvb set_frontend ops,
with works with both DVBv3 and DVBv5 calls.

[media] introduce gspca-stk1135: Syntek STK1135 driver
Hello,
this is a new gspca driver for Syntek STK1135 webcams. The code is completely
new, but register values are based on Syntekdriver (stk11xx) by Nicolas VIVIEN
(http://syntekdriver.sourceforge.net).
Only one webcam type is supported now - vendor 0x174f, device 0x6a31.
It's Asus F5RL laptop flippable webcam with MT9M112.
The camera works better than in Windows - initializes much faster and
provides more resolutions (the sensor can do almost any resolution - just
add it to the stk1135_modes[] - could this feature be somehow used by
applications to avoid SW scaling?).
Autoflip works too - when the camera is flipped around, the image is flipped
automatically.

[media] msi3101: change stream format 384
After feeding different signal levels using RF generator and looking
GNU Radio FFT sink I made decision to change bit shift 3 to bit shift
2 as there was very (too) huge visible leap in FFT sink GUI. Now it
looks more natural.

[media] msi3101: improve tuner synth calc step size
Allow stepless synthesizer configuration. With that change we lose
precision a little bit, as it is now between +-500Hz from the target.
It could be better but on that case calculation algorithm goes more
complex and atm there is more important things to do.
Two approach to improve which comes to my mind are:
1) select and use biggest suitable step
2) use greatest common divisor algo to find divisor for thresh & frac
when possible to avoid rounding errors, which is root of cause of
current +-500Hz inaccuracy.

[media] msi3101: enhance sampling results
It looks like there is some extra data carried to enhance sampling
results. When you tune to some some weak/empty channel those bits
are always zeroes. When you tune to some channel where is very
strong signals those bits are all zeroes.
Examining those 32-bits reveals shortly there is 16 pieces of 2-bit
numbers. Number seen are 0, 1 and 3 - for some reason 2 is not used.
I used that number to shift bits given amount to left, "increasing"
sampling resolution by 3-bits. It may be wrong, but after some testing
it still provides better signal.
