Fix bug by moving the i2c_unregister_device calls after deregistration
of dvb frontend.
The new style i2c drivers already destroys the frontend object at
i2c_unregister_device time.
When the dvb frontend is unregistered afterwards it leads to this oops:

There's a new version of Terratec H6 with uses USB ID
0ccd:10b2. This version is similar to the old one (with is
supported via the HTC entry), except that this one has the
eeprom on the second bus.
On this board, one side of this board is labeled with:
dvbc v2.0
The other side with:
94V-0, MO2, RK-4221 with huge digits: 1107
With those patches, the board is properly detected:

Hauppauge WinTV-dualHD is a USB 2.0 dual DVB-T/T2/C tuner with

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.

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

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.

em28xx_dvb_resume() unregisters i2c tuner, i2c demod, and dvb.
This erroneous cleanup results in i2c tuner, i2c demod, and dvb
devices unregistered and removed during resume. This error is a
result of merge conflict between two patches that went into 3.15.

The first hunk of this patch got merged wrong, likely due to some
changes at the em28xx resume code. Revert it to reapply it right.

Simplify the logic a little by removing one level of identation.
Also, it only makes sense to print something if the .fini callback
is actually doing something.

We can't free struct em28xx while one of the extensions is still
using it.
So, add a kref() to control it, freeing it only after the
extensions fini calls.

Add support for the Trident DRX-J driver, including a card profile for the

Thanks to Trident for allowing the release of this code under a BSD license,
and of course Hauppauge/PCTV for pushing for its release to the community.
