Hans-Frieder Vogt 182b967e11 [media] af9033: prevent unintended underflow
As spotted by Dan Carpenter <dan.carpenter@oracle.com> (thanks!), we have
improperly used an unsigned variable in a calculation that may result in a
negative number. This may cause an unintended underflow if the interface
frequency of the tuner is > approx. 40MHz.
This patch should resolve the issue, following an approach similar to what is
used in af9013.c.

Mauro Carvalho Chehab 8e30783b0b drxk: allow loading firmware synchrousnously
Due to udev-182, the firmware load was changed to be async, as
otherwise udev would give up of loading a firmware.

Add an option to return to the previous behaviour, async firmware
loads cause failures with the tda18271 driver.

Antti tested it with the following hardware:
        Hauppauge WinTV HVR 930C
        MaxMedia UB425-TC
        PCTV QuatroStick nano (520e)

Oliver Schinagl d67ceb3398 [media] Support for Asus MyCinema U3100Mini Plus
This is initial support for the Asus MyCinema U3100Mini Plus. The driver
in its current form gets detected and loads properly.
Scanning using dvbscan works without problems, Locking onto a channel
using tzap also works fine. Only playback using tzap -r + mplayer was
tested and was fully functional.
It uses the af9035 USB Bridge chip, with an af9033 demodulator. The tuner
used is the FCI FC2580.

Mauro Carvalho Chehab fccea74ff8 [media] Kconfig: merge all customise options into just one
Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.

That simplifies the life for users, as they can just keep
this untouched.

Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.
