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.

In this specific report:
CONFIG_DVB_USB_CXUSB=y
CONFIG_DVB_DIB7000P=m
But the same type of bug can happen if:
CONFIG_DVB_DIB7000P=m
and one of the bridge drivers is compiled builtin (cxusb, cx23885-dvb
and/or dib0700).
As a bonus, dib7000p won't be loaded anymore if the device uses

For almost all DVB frontends, there's just one function.
However, the dib7000p initialization can require up to 3
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
will be the first one to be called, whatever initialization
is needed.
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.

divider value for s600 devices
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.

- 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.

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.

Added support for the GOTVIEW SatelliteHD card which is based on
Montage M88DS3000 and works very well with this driver.

Since commit 7543f344e9b06afe86b55a2620f5c11b38bd5642 ("[media] m920x:
factor out a m920x_write_seq() function") building m920x.o triggers this
GCC warning:
drivers/media/usb/dvb-usb/m920x.c: In function ‘m920x_probe’:
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.

Terratec Cinergy S2 USB HD Rev.2 support.
This commit is a corrected cherry-pick of 03228792 which got reverted in
b7e38636 because it was rebased incorrectly and introduced compilation
errors.

The "Technisat SkyStar USB plus" is a TT-connect S-2400 clone, which the
V4L-DVB drivers already support. However, some of these devices (like
mine) come with a different USB PID 0x3009 instead of 0x3006.
There have already been patches simply overwriting the USB PID in
dvb-usb-ids.h. Of course these patches were rejected because they would
have disabled the 0x3006 PID.
This new patch adds the 0x3009 PID to dvb-usb-ids.h, and adds references
to it within the ttusb2.c driver. PID 0x3006 devices will continue to work.
The only difference between the two hardware models seems to be the
EEPROM chip. In fact, Windows BDA driver names the 0x3009 device with a
"(8 kB EEPROM)" suffix. In spite of that, the 0x3009 device works
absolutely flawlessly using the existing ttusb2 driver.

The ttusb2 module is already updated to recognize the TechnoTrend CT-3650
CI DVB C/T USB2.0 receiver in addition to the Pinnacle 400e. But if
MEDIA_SUBDRV_AUTOSELECT is used, the required tuner and demodulator
modules are not automatically selected. Here's a patch to fix that and add a
note of the CT-3650 to the online help of the ttusb2 module.
This patch applies cleanly to 3.7.6 and other 3.7.x kernels.

Fix bug introduced in 7757ddda6f4febbc52342d82440dd4f7a7d4f14f, where
instead of bit-negating the bitmask, the bit position was bit-negated
instead.
