Some apps which use read() start the streaming through a call to poll(),
this means that if another app has already claimed the device for streaming
(through for example a s_fmt, or a reqbufs), that the poll should fail instead
of getting passed through to vb2_poll.
We only check for this when the app is polling for reads, so that ctrl events
still work.

stb0899: fix the limits for signal strength values
stb0899_read_signal_strength() adds an offset to the result of the table lookup.
That offset must correspond to the lowest value in the lookup table, to make sure
the result doesn't get below 0, which would mean a "very high" value since the
parameter is unsigned.
'strength' and 'snr' need to be initialized to 0 to make sure they have a
defined result in case there is no "internal->lock".

It is mostly copy/paste of the 520e code with setting GPIO7 removed

I've worked on just released vanilla linux-3.3.0 kernel, so there may
be 1/2 lines offset to the internal working source, but most of the
code should apply cleanly.
I was able to get the DVB-C working (tuned and watched TV). Haven't
tested DVB-T (no signal atm).

The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner
instead of a tda18271c1 tuner as used in revision D1E9. To
account for this, we must hardcode the frontend configuration
to use the same IF frequency configuration for both revisions
of the device.
6MHz DVB-T is unaffected by this issue, as the recommended
IF Frequency configuration for 6MHz DVB-T is the same on both
c1 and c2 revisions of the tda18271 tuner.

I had learned through hard experience that dinking around with the DMA
descriptors while the C1_DESC_ENA enable bit was set is a recipe for all
kinds of truly malicious behavior on the hardware's part, regardless of
whether the DMA engine is actually operating at the time. That
notwithstanding, the driver did so dink, resulting in "green frame"
captures and the death of the system in random, spectacular ways.
Move the tweaking of C1_DESC_ENA to the same function that sets the
descriptor so we know that we'll never try to set a descriptor while that
bit is set.

Experience shows that, on the Armada platform, it can take as much as 120ms
for the DMA engine to actually shut down after it has been told to. So a

leave the DMA_ACTIVE flag set once things are down.
