This standard is not properly documented, but its settings are at
the tda18271dd driver, and are somewhat obvious, as they follow
the same logic as DVB-T 7MHz.

There is a bug on mxl5005s logic: when the bandwidth changes, but using
the same delivery system, the code discard the set_params()
reconfiguration request.
This was happening because, in the previous coding, the bandwidth
calculus were after the check for delivery system changes.
The previous patch changed the logic to estimate the bandwidth to
happend together with the changes at the delivery system.
So, with a one-statement change, it is possible to make the tuner to
reconfigure, in order to adjust to bandwidth changes. this will
likely fix issues on countries that use 7MHz/8MHz DVB-T channels.

This driver implements a fake get_bandwidth() callback. In
reallity, the tuner driver won't adjust its low-pass
filter based on a bandwidth, and were just providing a fake
method for demods to read whatever was "set".
This code is useless, as none of the drivers that use
this tuner seems to require a get_bandwidth() callback.
While here, convert set_params to use the DVBv5 way to pass
parameters to tuners.

Instead of just estimating the bandwidth for DVB-C annex A/C,
also fill it at the core for ATSC and DVB-C annex B. This
simplifies the logic inside the tuners, as all non-satellite
tuners can just use c->bandwidth_hz for all supported
delivery systems.
It could make sense to latter use it also for satellite
systems, as several DVB-S drivers have their own calculus.
However, on DVB-S2 the bw estimation is a little more complex,
and the existing drivers have some optimized calculus for
bandwidth. So, let's not touch on it for now.

SYS_DVBC_ANNEX_AC is an alias for SYS_DVBC_ANNEX_A. However,
the first one is incorrect, as not all devices support both.
So, replace its occurrences by the proper value (either
SYS_DVBC_ANNEX_A or both SYS_DVBC_ANNEX_A and SYS_DVBC_ANNEX_C).

dvb_register calls videobuf_dvb_register_bus, but if that returns
a failure the module will be unloaded without clearing the
value of core->gate_ctrl which will cause an oops in macros
called from video_open in cx88-video.c

Hi Mauro,
I have made a small mistake on this patch.
I forgot to increase number of num_device_descs to 4.

The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

There are some issues and miss-behaves at the dvb fe thread:
1) dvb_shutdown_timeout should be dvb_shutdown_timeout * HZ
instead of (dvb_shutdown_timeout * HZ + 1);
2) add a memory barrier to warrant that all CPU's will consider the
new value for release_jiffies;
3) wake up dvb thread also when fepriv->exit == DVB_FE_NO_EXIT.

It seems that a cut-and-past error were added by the last patch:
drivers/media/video/videobuf2-core.c: In function ‘vb2_qbuf’:
drivers/media/video/videobuf2-core.c:1099:14: warning: comparison between ‘enum v4l2_buf_type’ and ‘enum v4l2_memory’ [-Wenum-compare]
On all places V4L2_MEMORY_USERPTR is used, it is associated with
q->memory, and not b->type. So, the fix seems obvious.
