Since b9bf2eafaad9c1ef02fb3db38c74568be601a43a, the function
ds3000_firmware_ondemand() is called only once during init. This
locking scheme may have been useful when the firmware was loaded at
each tune.
Furthermore, it looks like this 'lock' was put in to prevent concurrent
access (and not recursion as the comments suggest). However, this open-
coded mechanism is anything but race-free and should have used a proper
mutex.Signed-off-by: Rémi Cardona

On gcc, enums are generally unsigned, except if a negative value
is declared. Due to that, warnings may happen there:

As other compilers might be using signed values, the better is to
keep the checks there, casting the value to avoid the warning.Signed-off-by: Mauro Carvalho Chehab

As spotted by Dan Carpenter (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.[crope@iki.fi: add Reported-by]

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:

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.Signed-off-by: Oliver Schinagl
