4e5552b23f media: Kconfig: fix some dvb-usb-v2 dependencies
There are some tuners used by a few pure DVB boards that use
internally V4L2 function calls. Due to that, such drivers now
depends on v4l2 core support, and can't be auto-selected
if !VIDEO_V4L2:

8cbaa12100 media: dvb-usb-v2: use DVB_USB_DEVICE() macro
Instead of using USB_DEVICE() macro directly, use the
DVB_USB_DEVICE() one, as other dvb-usb-v2 devices.

The usage of the new macro makes cleaner and easier to
parse the supported device names in a way that it would
be easily parseable to generate cardlists.

577a7ad33a media: docs: move driver-specific info to driver-api
Those documents don't really describe the driver API.

Instead, they contain development-specific information.

Yet, as the main index file describes the content of it as:

	"how specific kernel subsystems work
	 from the point of view of a kernel developer"

It seems to be the better fit.

It should be noticed, however, that several of those files
are outdated and will require further work in order to make

6bf05f7599 media: af9035: add support for Logilink VG0022A.
This includes a hack for the device as it returns only 0xff after a new
firmware is loaded. To quote Mauro:

"When the [...] firmware that came with the device is replaced
by a new one, any I2C data received from the tuner will be
replaced by 0xff.

Probably, the vendor firmware has some patch specifically
designed for this device. So, we can't replace by the generic
firmware.

The right solution would be to extract the [...] firmware from
the original driver and ask the driver to load the specifically
designed firmware, but, while we don't have that, the next best
solution is to just keep the original firmware at the device."

When the ite9135 code was merged with af9035, the formula was
lost. As we might need to slow down the speed for some devices,
add the formula again.

For Friio dvb cards, a distinct I2C algo was provided to support
some "long" I2C messages used in relaying tuner I2C via demod.
Since the other (generic) i2c algo in this module has been patched
to support those messages in a more generic way,
this patch replaces and integrates the device-specific i2c algo
with the generic one and simplifies the code.

6f5129e251 media: rtl28xxu: fix idle handling
Currently the IR receiver is put into idle mode after each interrupt.
However longer IR like NEC can be distributed over multiple interrupts,
so putting the IR into idle in the middle of such a message will break
decoding.

Every IR message has a trailing space of 0xbf (one less than
IR_IDE_LEN{0,1} which is programmed to 0xc0). So, set the timeout to that
value and rc-core will put the IR receiver into idle mode automatically.

95c520690f media: don't do a 31 bit shift on a signed int
On 32-bits archs, a signed integer has 31 bits plus on extra
bit for signal. Due to that, touching the 32th bit with something
like:

	int bar = 1 << 31;

has an undefined behavior in C on 32 bit architectures, as it
touches the signal bit. This is warned by cppcheck.

Instead, force the numbers to be unsigned, in order to solve this
issue.

    that, I think, will go to you directly later on.
 
  - A new document on how to use merges and rebases in kernel repos, and one
    on Spectre vulnerabilities.
 
  - Various improvements to the build system, including automatic markup of
    function() references because some people, for reasons I will never
    understand, were of the opinion that :c:func:``function()`` is
    unattractive and not fun to type.
 
  - We now recommend using sphinx 1.7, but still support back to 1.4.

458f69ef36 docs: timers: convert docs to ReST and rename to *.rst
The conversion here is really trivial: just a bunch of title
markups and very few puntual changes is enough to make it to
be parsed by Sphinx and generate a nice html.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

actual_length != wlen is the only error path which does not generate an

Also clean up the error paths - in case of an error, the remaining
code is skipped, and ret is returned. Skip setting ret and return
immediately (no cleanup necessary).

fdfa59cd63 media: dvbsky: Avoid leaking dvb frontend
Commit 14f4eaedda ("media: dvbsky: fix driver unregister logic") fixed
a use-after-free by removing the reference to the frontend after deleting
the backing i2c device.

This has the unfortunate side effect the frontend device is never freed
in the dvb core leaving a dangling device, leading to errors when the
dvb core tries to register the frontend after e.g. a replug as reported
here: https://www.spinics.net/lists/linux-media/msg138181.html

media: dvbsky: issues with DVBSky T680CI

===
[  561.119145] sp2 8-0040: CIMaX SP2 successfully attached
[  561.119161] usb 2-3: DVB: registering adapter 0 frontend 0 (Silicon Labs
Si2168)...
[  561.119174] sysfs: cannot create duplicate filename '/class/dvb/
dvb0.frontend0'
===

The use after free happened as dvb_usbv2_disconnect calls in this order:
- dvb_usb_device::props->exit(...)
- dvb_usbv2_adapter_frontend_exit(...)
  + if (fe) dvb_unregister_frontend(fe)
  + dvb_usb_device::props->frontend_detach(...)

Moving the release of the i2c device from exit() to frontend_detach()
avoids the dangling pointer access and allows the core to unregister
the frontend.

This was originally reported for a DVBSky T680CI, but it also affects
the MyGica T230C. As all supported devices structure the registration/
unregistration identically, apply the change for all device types.
