While this frontend provides a nice set of statistics, the
way it is currently reported to userspace is poor. Worse than
that, instead of using quality indicators that range from 0 to 65535,
as expected by userspace, most indicators range from 0 to 100.
Improve it by using DVBv5 statistics API. The legacy indicators
are still reported using the very same old way, but they're now
using a proper range (0 to 65535 for quality indicadors; 0.1 dB
for SNR).

It is confusing to merge both status updates with debug stuff.
Also, it is a better idea to move those status updates to

Instead of handling both DVB-T and ISDB-T at the same get_frontend

Currently, every time a message is sent or received, the endiannes
need to be fixed on big endian machines. This is currently done
on every call to the send API, and on every msg reception logic.
Instead of doing that, move it to the send/receive functions.
That simplifies the logic and avoids the risk of forgetting to

I've chosen not to follow the suggestions in that thread since gamma_width is
really a different property from data_size. What you really want is to know if
gamma_width fits inside data_size and for that you need to translate each
enum into a maximum bit number so you can safely compare the two.
So I put in two static inline translation functions instead, keeping the rest
of the code the same (except for fixing the 'gama' typo).

It turned out that some devices return less bytes then requested via i2c when
ALL of the following 3 conditions are met:
- i2c bus B is used
- there was no attempt to write to the specified slave address before
- no device present at the specified slave address
With the current code, this triggers an -EIO error and prints a message to the
system log.
Because it can happen very often during device probing, it is better to ignore
this error and bail out silently after the follwing i2c transaction success
check with -ENODEV.

Since commit 7543f344e9 ("[media] m920x:

drivers/media/usb/dvb-usb/m920x.c:91:6: warning: ‘ret’ may be used uninitialized in this function [-Wuninitialized]
This warning is caused by m920x_write_seq(), which is apparently inlined
into m920x_probe(). It is clear why GCC thinks 'ret' may be used
uninitialized. But in practice the first seq->address will always be
non-zero when this function is called. That means we can change the
while()-do{} loop into a do{}-while() loop. And that suffices to make
GCC see that 'ret' will not be used uninitialized.

Ensure the driver gets always at least its minimum required
number of buffers allocated by checking actual number of
allocated buffers in vb2_reqbufs(). And free any partially
allocated buffer queue with signaling an error to user space.
Without this patch applications may wait forever to dequeue
a filled buffer, because the hardware didn't even start after
VIDIOC_STREAMON, VIDIOC_QBUF calls, due to insufficient number
of empty buffers.

Not all drivers use monotonic timestamps. This patch adds a way to set the
timestamp type per every queue.
In addition, set proper timestamp type in drivers that I am sure that use
either MONOTONIC or COPY timestamps. Other drivers will correctly report
UNKNOWN timestamp type instead of assuming that all drivers use monotonic
timestamps.

The 417 support doesn't work. Until someone can dig into this driver to
figure out why it isn't working the 417 support is disabled.
Sometimes you can actually stream a bit, but very soon the whole machine
crashes, so something is seriously wrong.
For the record, this was not introduced by my recent changes to this driver,
it was broken before that.
