There is an special lookup code that is called when
SMS_BOARD_UNKNOWN. The logic there is bogus and will cause
an oops, as .type is SMS_UNKNOWN_TYPE (-1).
As the code would do:
return smscore_fw_lkup[type][mode];
That would mean that it would try to go past the
smscore_fw_lkup table.
So, just remove that bogus code, simplifying the logic.

There are two ways to specify firmware for siano devices: a
per-device ID and a per-device type.
The per-device type logic is currently made by a 11x9 string
table, sparsely filled. It is very hard to read the table at
the source code, as there are too much "none" filling there
("none" there is a way to tell NULL).
Instead of using such problematic table, convert it into an
easy to read table, where the unused values will be defaulted
to NULL.
While here, also simplifies a little bit the logic and print
a message if an user-selected mode doesn't exist.

This seems to be ever broken. That's the status report with
Firmware 2.1, before adding support for sms2270 is:
[22273.787218] smsdvb_onresponse: MSG_SMS_GET_STATISTICS_RES
[22273.792592] IsRfLocked = 1
[22273.792592] IsDemodLocked = 1
...
[22273.792598] TransmissionMode = -64
...
(all unshown fields are filled with zeros)
Of course, transmission mode being a negative number is wrong.
So, we need to take a deeper look on it.
With the debugfs patches applied, it is possible to see that, instead
of filling StatisticsType with 5, and FullSize with the size of the
payload (this is what happens with sms2270 and firmware 8.1),
those fields are also initialized with zero:
StatisticsType = 0 FullSize = 0
IsRfLocked = 1 IsDemodLocked = 1 IsExternalLNAOn = 0
SNR = 0 dB RSSI = 0 dBm InBandPwr = 0 dBm
CarrierOffset = 0 Bandwidth = 0 Frequency = 0 Hz
TransmissionMode = -64 ModemState = 0 GuardInterval = 0
SystemType = 0 PartialReception = 0 NumOfLayers = 0
SmsToHostTxErrors = 0
The data under "TransmissionMode" varies according with the signal,
and it is negative. It also matches the value for InBandPwr when
the tuner is on DVB-T (ok, signal doesn't lock, but the power level
should be about the same with the antena fixed, and measured at about
the same time).
So, there's a very high chance that, when StatisticsType is zero, the
signal strength is at the same position as Transmission Mode.
So, discard all other parameters, and provide only signal/rf lock and
signal strength if StatisticsType is 0, for ISDB-T.

Right now, the driver sends DVB data even before tunning.
It was noticed that this may lead into some mistakes at DVB
decode, as the PIDs from wrong channels may be associated with
another frequency, as they may already be inside the PID buffers.
So, prevent it by not feeding DVB demux with data while there's no
feed or while the device is not tuned.

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,

Improve it by using DVBv5 statistics API. The legacy indicators

The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.
Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.
Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.
Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).
The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).
This patch separate the different usages in preparation for
upcoming patches.
Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.
The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.

In the past, it was possible to have either DVB or V4L2 core
as module and the other as builtin. Such config never make much
sense, and created several issues in order to make the Kconfig
dependency to work, as all drivers that depend on both (most
TV drivers) would need to be compiled as 'm'. Due to that,
the VIDEO_MEDIA config option were added.
Instead of such weird approach, let's just use the MEDIA_SUPPORT
=y or =m to select if the media subsystem core will be either
builtin or module, simplifying the building system logic.
Also, fix the tuners configuration, by enabling them only if
a tuner is required. So, if just webcam/grabbers support is
selected, no tuner option will be selected. Also, if only digital
TV is selected, no analog tuner support is selected.
That removes the need of using EXPERT customise options, when
analog TV is not selected.

Change the main items to:
<m> Multimedia support --->
[ ] Cameras/video grabbers support
[ ] Analog TV support
[ ] Digital TV support
[ ] AM/FM radio receivers/transmitters support
[ ] Remote Controller support
This provides an interface that is clearer to end users that
are compiling the Kernel, and will allow the building system
to automatically unselect drivers for unused functions.

xc5000 is just a tuner, not a decoder, so both DMB-TH and ISDB-T should
work properly there: it is just a matter of teaching the driver what
saw filter should be used and how to calculate the center frequency.

Implement API support to return AFC frequency shift, as this device
supports it. The only other driver that implements it is tda9887,
and the frequency there is reported in Hz. So, use Hz also for this
tuner.

There are several bugs at the signal strength algorithm:
- It is using logical OR, instead of bit OR;
- It doesn't wait up to 18 ms as it should;
- the strength range is not ok.
Rework on it, in order to make it work.

Change the firmware logic to use request_firmware_nowait(), and
to preserve the loaded firmwares in memory, to reduce the risk
of troubles with buggy userspace apps.
With this change, while the firmware is being loaded, the driver
will return -EAGAIN to any calls. If, for some reason, firmware
failed to be loaded from userspace, it will return -ENODEV.

Besides the usual inconsistencies in input enumeration there was also a
kernel crash if you tried to poll on a vbi node. The checks for sliced
vbi output vs vbi capture were not complete enough.

The querycap ioctl returned an incorrect version number and incorrect
capabilities (mixing up vbi and video caps).
The reason for that was that video nodes could do vbi activities: that
should be separated between the vbi and video nodes.
There were also a few minor problems with dbg_g/s_register that have
been resolved. The mxb/saa7146 driver now passes the v4l2_compliance tests.
