Addresses the following, which introduced a regression itself:
Commit 509f89652f83 ("media: em28xx: fix a regression with HVR-950")
The regression fix breaks dual transport stream support. Currently,
when a tuner starts streaming it sets alt mode on the USB interface.
The problem is, in a dual tuner model, both tuners share the same
USB interface, so when the second tuner becomes active and sets alt
mode on the interface it kills streaming on the other port.
This patch addresses the regression by only setting alt mode
on the USB interface during em28xx_start_streaming, if the
device is not a dual tuner model. This allows all older and
single tuner devices to explicitly set alt mode during stream
startup. Testers report both isoc and bulk DualHD models work
correctly with the alt mode set only once, in em28xx_dvb_init.

The use of a hard coded i2c address breaks the creation of the
second tuner in DualHD 01595 models. The issue is compounded
by lack of any error message stating that a driver failed
initialization. Use addr, which contains the correct address
for each tuner.

From now on, I'll start using my @kernel.org as my development e-mail.
As such, let's remove the entries that point to the old
mchehab@s-opensource.com at MAINTAINERS file.
For the files written with a copyright with mchehab@s-opensource,
let's keep Samsung on their names, using mchehab+samsung@kernel.org,
in order to keep pointing to my employer, with sponsors the work.
For the files written before I join Samsung (on July, 4 2013),
let's just use mchehab@kernel.org.
For bug reports, we can simply point to just kernel.org, as
this will reach my mchehab+samsung inbox anyway.

The module probing logic there is a way more complex than
it should be, and requires some special magic to avoid
stack overflows when KASAN is enabled.
Solve it by creating ancillary functions to setup the
platform data and request module.
Now, the probing functions are cleaner and easier to understand.
As a side effect, the size of the module was reduced by
about 9.7% on x86_64:

With CONFIG_KASAN, the init function uses a large amount of kernel stack:
drivers/media/usb/em28xx/em28xx-dvb.c: In function 'em28xx_dvb_init.part.4':
drivers/media/usb/em28xx/em28xx-dvb.c:2061:1: error: the frame size of 3232 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
Using gcc-7 with -fsanitize-address-use-after-scope makes this even worse:
drivers/media/usb/em28xx/em28xx-dvb.c: In function 'em28xx_dvb_init':
drivers/media/usb/em28xx/em28xx-dvb.c:2069:1: error: the frame size of 4280 bytes is larger than 3072 bytes [-Werror=frame-larger-than=]
By splitting out each part of the switch/case statement that has its own local
variables into a separate function, no single one of them uses more than 500 bytes,
and with a noinline_for_stack annotation we can ensure that they are not merged
back together.

Now that we're storing usb_interface at em28xx struct,
there's no good reason to keep storing usb_device, as we can
get it from usb_interface. So, get rid of it.

The usb_device->dev is not the right device for dev_foo() calls.
Instead, it should use usb_interface->dev.

Instead of using pr_foo(), use dev_foo(), with provides a
better output. As this device is a multi-interface one,
we'll set the device name to show the chipset and the driver
used.
While here, get rid of printk continuation messages.

There are still several places with printk's called directly.
Convert them to pr_foo() macros, except for the debug printk's,
as those are enabled via modprobe vars.
While here, realign the pr_foo() arguments to match the
recommended CodingStyle.

Due to the 80-cols checkpatch warnings, several strings
were broken into multiple lines. This is not considered
a good practice anymore, as it makes harder to grep for
strings at the source code. So, join those continuation

Hauppauge WinTV-dualHD is a USB 2.0 dual DVB-T/T2/C tuner with
following components:
USB bridge: Empia EM28274 (chip id is the same as EM28174)
Demodulator: 2x Silicon Labs Si2168-B40
Tuner: 2x Silicon Labs Si2157-A30
This patch adds support only for the first tuner.
The demodulator needs firmware, available for example here:
http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/
The demodulators sit on the same I2C bus and their addresses
are 0x64 and 0x67. The tuners are behind the demodulators and
their addresses are 0x60 and 0x63.

PX-BCUD has the following components:
USB interface: Empia EM28178
Demodulator: Toshiba TC90532 (works by code for TC90522)
Tuner: Next version of Sharp QM1D1C0042
em28xx_dvb_init(): add init code for PLEX PX-BCUD with calling
px_bcud_init() that does things like pin configuration.
qm1d1c0042_init(): support the next version of QM1D1C0042, change to
choose an appropriate array of initial registers by reading chip id.

As si2157 doesn't use the subdev, but has instead a binding

The Terratec Cinergy T XS is a DVB-T receiver with no analog TV tuner.
This patch adds support for the cards carrying the mt2060 tuner; it's
unclear whether there are cards sold under the same name which use a
different tuner.
As long as there are no reports of such cards, and indeed as long as
there are no working drivers for them, we assume that the USB device
[0ccd:0043] is carrying the mt2060 tuner.

The chips supported by the si2157 driver have two IF outputs (either
pins 12+13 or pins 9+11). Instead of hardcoding the output to be used
add an option to choose which output shall be used.
As this patch changes the default behaviour, the IF interface is
specified in each driver currently using si2157 driver. This is to
keep bisectability.

This patch is basically produced while testing a tool that
Joe Perches sent upstream sometime ago:
https://lkml.org/lkml/2014/7/11/794
I used it with those arguments:
$ reformat_with_checkpatch.sh drivers/media/usb/em28xx/em28xx*.[ch]
It actually produced 24 patches, with is too much, and showed
interesting things: gcc produced different codes on most of the
patches, even with just linespace changes. The total code data
remained the same on all cases I checked though.
Anyway, provided that we fold the resulting patches, this tool
seems useful.

Terratec Cinergy T2 Stick HD [eb1a:8179] is a USB DVB-T/T2/C tuner that
contains following components:
* Empia EM28178 USB bridge
* Silicon Labs Si2168-A30 demodulator
* Silicon Labs Si2146-A10 tuner
I don't have the remote, so the RC_MAP is a best guess based on the pictures of
the remote controllers and other supported Terratec devices with a similar
remote.

Change em28xx_dvb_fini() to set fe exit flag to DVB_FE_DEVICE_REMOVED
when device is disconnected. em28xx maintains device disconnect status
in em28xx device. fe drivers will be able to now check the fe exit
status to avoid accessing the device, from their release interfaces
when called from disconnect path. This change depends on dvb-core
change that exports fe exit flag by moving it from fepriv to fe.
