Refactor out the common parts of stv6110x_probe() and stv6110x_attach()
into separate functions.
This provides the needed functionality to use dvb_module_probe() instead
of dvb_attach()!

Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.
That way the V4L2 core knows what the capabilities of the
video device are.
But this only really works if all drivers use this, so convert
this SDR driver in this patch.

The phylink conflict was between a bug fix by Russell King
to make sure we have a consistent PHY interface mode, and
a change in net-next to pull some code in phylink_resolve()
into the helper functions phylink_mac_link_{up,down}()
On the dp83867 side it's mostly overlapping changes, with
the 'net' side removing a condition that was supposed to
trigger for RGMII but because of how it was coded never
actually could trigger.

'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

Embedded systems often connect to sensors or other multimedia
subdevices directly. Currently, to be able to select such a
subdevice (e.g. CONFIG_VIDEO_OV5640) disabling of the auto-
select config option is needed (CONFIG_MEDIA_SUBDRV_AUTOSELECT).
This is inconvenient as the ancillary drivers for a particular
device then need to be selected manually.
Allow to select drivers manually while keeping the auto-select
feature in case EXPERT (selected by EMBEDDED) is enabled.

si2165_readreg8() may fail. Looking into si2165_readreg8(), we will find
that "val_tmp" will be an uninitialized value when regmap_read() fails.
"val_tmp" is then assigned to "val". So if si2165_readreg8() fails,
"val" will be a random value. Further use will lead to undefined
behaviors. The fix checks if si2165_readreg8() fails, and if so, returns
its error code upstream.

Ref: https://bugzilla.kernel.org/show_bug.cgi?id=199323
Users are experiencing problems with the DVBSky S960/S960C USB devices
since the following commit:
9d659ae: ("locking/mutex: Add lock handoff to avoid starvation")
The device malfunctions after running for an indeterminable period of
time, and the problem can only be cleared by rebooting the machine.
It is possible to encourage the problem to surface by blocking the
signal to the LNB.
Further debugging revealed the cause of the problem.

Two i2c messages are sent to perform a reset in m88ds3103_set_frontend:
a. 0x07, 0x80
b. 0x07, 0x00
However, as shown in the capture, the regmap mutex is being handed over
to another thread (ts2020_stat_work) in between these two messages.
>From here, the device responds to every i2c message with an 07 message,
and will only return to normal operation following a power cycle.
Use regmap_multi_reg_write to group the two reset messages, ensuring
both are processed before the regmap mutex is unlocked.

A typo in code cleanup commit db9c1007bc07 ("media: lgdt330x: do
some cleanups at status logic") broke the FE_HAS_LOCK reporting
for 3303 chips by inadvertently modifying the register mask.
The broken lock status is critial as it prevents video capture
cards from reporting signal strength, scanning for channels,
and capturing video.
Fix regression by reverting mask change.

There is a smatch warning:
drivers/media/dvb-frontends/drxk_hard.c: drivers/media/dvb-frontends/drxk_hard.c:1478 scu_command() error: we previously assumed 'parameter' could be null (see line 1467)
Telling that parameter might be NULL. Well, it can't, due to the
way the driver works, but it doesn't hurt to add a check, in order
to shut up smatch.

For no apparent reason this code casts away the const of the const u16 arrays, and it
also takes the address of an array. While that's ignored in C I think smatch gets confused
by it.

Tuners should report frequencies in Hz. That works fine on most
drivers, but, in the case of dvb-pll, some settings are for
satellite tuners, while others are for terrestrial/cable ones.
The code was trying to solve it at probing time, but that doesn't
work, as, when _attach is called, the delivery system may be wrong.
Fix it by ensuring that all frequencies are in Hz at the per-tuner
max/min values.
While here, add a debug message, as this would help to debug any
issues there.

Pull new experimental media request API from Mauro Carvalho Chehab:
"A new media request API
This API is needed to support device drivers that can dynamically
change their parameters for each new frame. The latest versions of
Google camera and codec HAL depends on such feature.
At this stage, it supports only stateless codecs.
It has been discussed for a long time (at least over the last 3-4
years), and we finally reached to something that seem to work.
This series contain both the API and core changes required to support
it and a new m2m decoder driver (cedrus).
As the current API is still experimental, the only real driver using
it (cedrus) was added at staging[1]. We intend to keep it there for a
while, in order to test the API. Only when we're sure that this API
works for other cases (like encoders), we'll move this driver out of
staging and set the API into a stone.
[1] We added support for the vivid virtual driver (used only for
testing) to it too, as it makes easier to test the API for the ones
that don't have the cedrus hardware"

Consumer devices are provided with a wide different range of types
supported by the same driver, allowing different configutations.
In order to make easier to setup media controller links, "taint"
pads with the signal type it carries.
While here, get rid of DEMOD_PAD_VBI_OUT, as the signal it carries
is actually the same as the normal video output.
The difference happens at the video/VBI interface:
- for VBI, only the hidden lines are streamed;
- for video, the stream is usually cropped to hide the
vbi lines.

As pointed by Daniel Scheller <d.scheller@gmx.net>, sparse
warns that a segment may fall through. We're deprecating
this warning in favor of gcc 8 equivalent warning.
In this specific case, the code for DVB-S applies for DVB-S2.
In a matter of fact, several things there (like rolloff
factor logic) assume that the transponder is DVB-S2.
So, add the corresponding fall-trough markup, for gcc to
properly ignore it.
