This patches fixes an ancient bug in the dvb_usb_af9005 driver, which
has been reported at least in the following threads:
https://lkml.org/lkml/2009/2/4/350https://lkml.org/lkml/2014/9/18/558
If the driver is compiled in without any IR support (neither
DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in
af9005_usb_module_init() return pointers != NULL although the IR
symbols are not available.
This leads to the following oops:

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).
Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.
The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.
Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.

TechnoTrend TT-connect CT2-4650 CI (0b48:3012) is an USB DVB-T2/C tuner with
the following components:
USB interface: Cypress CY7C68013A-56LTXC
Demodulator: Silicon Labs Si2168-A20
Tuner: Silicon Labs Si2158-A20
CI chip: CIMaX SP2HF
The firmware for the tuner is the same as for TechnoTrend TT-TVStick CT2-4400.
See https://www.mail-archive.com/linux-media@vger.kernel.org/msg76944.html
The demodulator needs a firmware that can be extracted from the Windows drivers.
File ttConnect4650_64.sys should be extracted from
http://www.tt-downloads.de/bda-treiber_4.1.0.4.zip (MD5 sum below).
3464bfc37a47b4032568718bacba23fb ttConnect4650_64.sys
Then the firmware can be extracted:
dd if=ttConnect4650_64.sys ibs=1 skip=273376 count=6424 of=dvb-demod-si2168-a20-01.fw
The SP2 CI module requires a definition of a function cxusb_tt_ct2_4650_ci_ctrl
that is passed on to the SP2 driver and called back for CAM operations.

The basic API of rc-core used to be:
dev = rc_allocate_device();
dev->x = a;
dev->y = b;
dev->z = c;
rc_register_device();
which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:
dev = rc_allocate_device();
dev->x = a;
rc_set_allowed_protocols(dev, RC_BIT_X);
dev->z = c;
rc_register_device();
There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.
This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

the RC RX packet is defined as:
struct dib0700_rc_response {
...
u8 not_system;
u8 system;
...
u8 data;
u8 not_data;
The NEC protocol transmits in the order:
system
not_system
data
not_data
Note that the code defines the NEC extended scancode as:
scancode = be16_to_cpu(poll_reply->system16) << 8 | poll_reply->data;
i.e.
scancode = poll_reply->not_system << 16 |
poll_reply->system << 8 |
poll_reply->data;
Which, if the order *is* reversed, would mean that the scancode that
gets defined is in reality:
scancode = poll_reply->system << 16 |
poll_reply->not_system << 8 |
poll_reply->data;
Which is the same as the order used in drivers/media/rc/ir-nec-decoder.c.
This patch changes the code to match my assumption (the generated scancode
should, however, not change).

Exporting multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.
The bug happens when:
CONFIG_DVB_DIB8000=m
CONFIG_DVB_USB_DIB0700=y
As a bonus, dib8000 won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.

Well, what we call as "foo_attach" is the method that should
be called by the dvb_attach() macro.
It should be noticed that the name "dvb_attach" is really a
bad name and don't express what it does.
dvb_attach() basically does three things, if the frontend is
compiled as a module:
- It lookups for the module that it is known to have the
given symbol name and requests such module;
- It increments the module usage (anonymously - so lsmod
doesn't print who loaded the module);
- after loading the module, it runs the function associated
with the dynamic symbol.
When compiled as builtin, it just calls the function given to it.
As dvb_attach() increments refcount, it can't be (easily)
called more than once for the same module, or the kernel
will deny to remove the module, because refcount will never
be zeroed.
In other words, the function name given to dvb_attach()
should be one single symbol that will always be called
before any other function on that module to be used.
For almost all DVB frontends, there's just one function,
but, on dib8000, there are several exported symbols.
We need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.
So, let's rename this function, in order to prepare for
a next patch that will add a new attach() function that
will be the only one exported by this module.

functions to be called:
- dib7000p_get_i2c_master;
- dib7000p_i2c_enumeration;
- dib7000p_init (before this patch dib7000_attach).
(plus a bunch of other functions that the bridge driver will
need to call).
As we need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that

So, let's rename the function that probes and init the hardware
to dib7000p_init.
A latter patch will add a new dib7000p_attach that will be
used as originally conceived by dvb_attach() way.

drivers/media/usb/dvb-usb/dibusb-common.c:124:1: warning: 'dibusb_i2c_msg' uses dynamic stack allocation [enabled by default]
Instead, let's enforce a limit for the buffer to be the max size of
a control URB payload data (64 bytes).

When the tuner part of the ds3000 driver was split to share code with the m88rs2000 driver, the ts2020 driver used
the frequency divider value from the m88rs2000 driver. However the ds3000 driver requires a different value, and this
resulted in some frequecies being invisible to the tuner. This patch adds back in the value needed for the ds3000 driver
and configured as an option in the dw2102 frontend driver.
It may also apply to su3000 devices, which use the same ds3000 driver, but for now it is only applied to the s660 device.

Pull media update from Mauro Carvalho Chehab:
- OF documentation and patches at core and drivers, to be used by for
embedded media systems
- some I2C drivers used on go7007 were rewritten/promoted from staging:
sony-btf-mpx, tw2804, tw9903, tw9906, wis-ov7640, wis-uda1342
- add fimc-is driver (Exynos)
- add a new radio driver: radio-si476x
- add a two new tuners: r820t and tuner_it913x
- split camera code on em28xx driver and add more models
- the cypress firmware load is used outside dvb usb drivers. So, move
it to a common directory to make easier to re-use it
- siano media driver updated to work with sms2270 devices
- several work done in order to promote go7007 and solo6x1x out of
staging (still, there are some pending issues)
- several API compliance fixes at v4l2 drivers that don't behave as
expected
- as usual, lots of driver fixes, improvements, cleanups and new device
addition at the existing drivers.

The intend of this patch is to improve the support of the dib7090 and
dib7790. The AGC1 min value is set to 32768 by default. The actual AGC1 min
and the external attenuation are controled depending on the received RF
level.

The intend of this patch is to improve the support of the dib8096. The PLL
parameters are not automatically computed. The limit to set/unset external
diode for attenuation has been updated. The TFE8096P board is using the
new I2C API.

drivers/media/usb/dvb-usb/m920x.c:91:6: warning: "ret" may be used uninitialized in this function [-Wuninitialized]
drivers/media/usb/dvb-usb/m920x.c:70:6: note: "ret" was declared here
This is real, if a remote control has an empty initialization sequence
we would get success or failure randomly.
OTOH the initialization of ret in m920x_init is needless, the function
returns with an error as soon as an error happens, so the last return
can only be a success and we can hard-code 0 there.
