[media] ts2020: Provide DVBv5 API signal strength
Provide a DVBv5 API signal strength. This is in units of 0.001 dBm rather
than a percentage.
>From Antti Palosaari's testing with a signal generator, it appears that the
gain calculated according to Montage's specification if negated is a
reasonable representation of the signal strength of the generator.
To this end:
(1) Polled statistic gathering needed to be implemented in the TS2020 driver.
This is done in the ts2020_stat_work() function.
(2) The calculated gain is placed as the signal strength in the
dtv_property_cache associated with the front end with the scale set to
FE_SCALE_DECIBEL.
(3) The DVBv3 format signal strength then needed to be calculated from the
signal strength stored in the dtv_property_cache rather than accessing
the value when ts2020_read_signal_strength() is called.

[media] TS2020: Calculate tuner gain correctly
The TS2020 and TS2022 tuners take an input from the demodulator indicating the
AGC setting on that component that is then used to influence the tuner's own
gain. This should be taken into account when calculating the gain and signal
strength.
Further, the existing TS2020 driver miscalculates the signal strength as the
result of its calculations can exceed the storage capacity of the 16-bit word
used to return it to userspace.
To this end:
(1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that
the tuner can call to get the AGC PWM value from the demodulator.
(2) Modify the TS2020 driver to calculate the gain according to Montage's
specification with the adjustment that we produce a negative value and
scale it to 0.001dB units (which is what the DVBv5 API will require):
(a) Callback to the demodulator to retrieve the AGC PWM value and then
turn that into Vagc for incorporation in the calculations. If the
callback is unset, assume a Vagc of 0.
(b) Calculate the tuner gain from a combination of Vagc and the tuner's RF
gain and baseband gain settings.
(3) Turn this into a percentage signal strength as per Montage's
specification for return to userspace with the DVBv3 API.
(4) Provide a function in the M88DS3103 demodulator driver that can be used to
get the AGC PWM value on behalf of the tuner.
(5) The ts2020_config.get_agc_pwm function should be set by the code that
stitches together the drivers for each card.
For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022,
set the get_agc_pwm function to point to m88ds3103_get_agc_pwm.
I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022.
Thanks to Montage for providing access to information about the workings of
these parts.

A bug is present on the initial 6 - when changing transponders
one of two PAT packets from the old transponder would be included

transpired with userspace programs complaining about services
missing, because they are seeing a PAT that they would not be

[media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.
So, let's do it.
This patch was generated by this shell script:
for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

[media] vivid: move PRINTSTR to separate functions
Commit
84cb7be43cec12868e94163c99fdc34c0297c3b8 broke vivid-tpg
(uninitialized variable p).
This patch takes a different approach: four different functions are
created, one for each PRINTSTR version.
In order to avoid the 'the frame size of 1308 bytes is larger than 1024
bytes' warning I had to mark those functions with 'noinline'. For
whatever reason gcc seems to inline this aggressively and it is doing
weird things with the stack.
I tried to read the assembly code, but I couldn't see what exactly it
was doing on the stack.

Simplify cobalt_g/try_fmt_vid_cap by not setting the colorspace fields in

v4l2_fill_mbus_format in cobalt_s_fmt_vid_out which allows the get_fmt
