e39b8e945e media: ngene: check for CXD2099AR presence before attaching
Currently, if there's no CXD2099AR attached to any expansion connector of
the ngene hardware, it will complain with this on every module load:

    cxd2099 1-0040: No CXD2099AR detected at 0x40
    cxd2099: probe of 1-0040 failed with error -5
    ngene 0000:02:00.0: CXD2099AR attach failed

This happens due to the logic assuming such hardware is always there and
blindly tries to attach the cxd2099 I2C driver. Rather add a probe
function (in ngene-cards.c with a prototype in ngene.h) to check for
the existence of such hardware before probing, and don't try further if
no CXD2099 was found.

7d5397d47f media: ngene: add XO2 module support
Detect and initialise modules equipped with XO2 interfaces (Lattice
MachXO2). This requires a few more I2C transfer functions which this adds
as well. Defines for the different possible (available) module types are
added to ngene.h. The support for the actual tuners contained on these
addon modules is kept separate from this commit and is being added with
the next commits.

The xo2names array is temporarily marked __maybe_unused to silence a
corresponding compiler warning at this stage.

1c2ad82e53 media: ngene: support STV0367 DVB-C/T DuoFlex addons
Add support for STV0367+TDA18212 based DuoFlex CT addon modules. For this,
add a demod probe function and all necessary demod/tuner attach functions
which use existing auxiliary drivers (stv0367 and tda18212) to support
this hardware. As tda18212 is an I2C client driver, proper cleanup code
is added to the deregistration sequence in ngene-core. To not cause use-
after-free situations when there's a CXD2099 I2C client connected, which
is rather freed in ngene-core.c:cxd_detach(), add i2c_client_fe to struct
ngene_channel to keep track if the i2c_client was allocated by a frontend
driver, rather than the CI code paths. Also move the I2C access functions
to the top of the file and add the required read_regs() function for the
tda18212 ping to work.

This adds autoselection (if MEDIA_SUBDRV_AUTOSELECT) of the STV0367 demod
driver and TDA18212 tuner driver to Kconfig aswell.

66a4c0c749 media: ngene: use defines to identify the demod_type
Make it more clear which demod_type is used for which hardware by having
defines for the possible demod_type values. With that, change the
demod_type evaluation in tuner_attach_probe() to a switch-case instead
of an if() for each possible value.

0df289a209 [media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

4c62e9764a Drivers: media: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
