7ef66759a3 [media] drx-j: Use checkpatch --fix to solve several issues
Instead of manually fixing the issues, use the --fix experimental
checkpatch. That solves a bunch of checkpatch issues.

61263c751b [media] drx-j: get rid of most of the typedefs
There are lots of typedefs there. Let's get rid of them.

Most of the work here is due to this small script:

	if [ "$3" == "" ]; then
		echo "usage: $0 type DRXName drx_name"
	fi
	t=$1; f=$2; g=$3
	for i in *.[ch]; do
		sed s,"p${f}_t","$t $g *",g <$i >a && mv a $i && \
		sed s,"${f}_t","$t $g",g <$i >a && mv a $i
	done

Just kept there the function typedefs, as those are still useful.

Yet, all those tuner_ops can likely be just removed on a latter
cleanup patch.

8272d0a0c0 [media] m88rs2000: prevent frontend crash on continuous transponder scans
Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol
rate more than 3000000 and delay of 3000ms less than this.

Adding min delay prevents crashing the frontend on continuous
transponder scans. Other dvb_frontend_tune_settings remain as default.

This makes very little time difference to good channel scans, but slows down
the set frontend where lock can never be achieved i.e. DVB-S2.

So, let's remove the bad code.

44b9055b4b [media] m88ds3103: use I2C mux for tuner I2C adapter
Switch standard I2C adapter to muxed I2C adapter.

David reported that I2C adapter implementation caused deadlock.
I discussed with Jean and he suggested to implement it as a
multiplexed i2c adapter because tuner I2C bus could be seen like
own I2C segment.

0400c5354a [media] dib8000: improve block statistics
PER/UCB statistics are collected once on each 1 second.
However, it doesn't provide the total number of packets
needed to calculate PER.

Yet, as we know the bit rate, it is possible to estimate
such number. So, do it.

7a9d85d555 [media] dib8000: Fix UCB measure with DVBv5 stats
On dib8000, the block error count is a monotonic 32 bits register.
With DVBv5 stats, we use a 64 bits counter, that it is reset
when a new channel is tuned.

Change the UCB counting start from 0 and to be returned with
64 bits, just like the API requests.

42ff76bdb0 [media] dib8000: make a better estimation for dBm
Use multiple linear segments to better interpolate the dBm
for the signal strength.

The table that converts from linear strength to dB was
empirically determinated with the help of a signal generator
(DTA-2111).

The entries from -35dBm to -22.5dBm were taken using just
the signal generator and the board.

For the entries from -36dBm to -51dBm, a 16 dB tap was used,
in order to extend its range.

Signals below to -51dBm are just linearly interpolated.

b4600d70c0 [media] dib8000: estimate strength in dBm
Better to have Signal strength in dB.
This takes a very rough estimation for the signal strength,
that was calibrated using a Dektec DTA-2111 Gold RF generator
and a Pixelview dib8076 stick.

It estimates the signal strength using a linear equation where:
	- the max is -22.5 dBm, with returns 55953
	- the min is -35.0 dBm, with returns 50110

With -22dBm, the signal strengh is returned as 65535.
Unfortunately, the min strength generated with DTA-2111 is
-35dBm.

It should be noticed that approximating it by a linear equation
is not right. I should probably be splitting it into 0.5 dB
linear segments, in order to get a higher precision, just like
it is done on mb86a20s, but that would force me to add some
attenuators, in order to get dB levels below -35dBm, which is,
btw, strong enough to get signal lock.

The advantage of DVBv5 stats is that it allows adding proper
scales to all measures. use it for this frontend.

This patch adds a basic set of stats, basically cloning what's already
provided by DVBv3 API. Latter patches will improve it.
