V4L/DVB (10170): tuner-simple: prevent possible OOPS caused by divide by zero error
A user reported the following OOPS with his pcHDTV HD5500 card, which
uses a cx88 PCI bridge with a LG-TDVS-H06xF frontend module, made up
of a TUA6034 tuner, TDA988x IF demod, and LG DT3303 ATSC/QAM demod.
Somehow, tuner-core gets loaded before the digital driver configures
the tuner, and tuner-core somehow incorrectly sets the tuner type to
LG NTSC (TAPE series) instead of LG TDVS-H06xF. This tuner type does
not have the tuning stepsize defined, so an OOPS occurs during the
digital tune function.
We still dont know how the type gets set incorrectly in the first place.
The user has a tainted kernel with a binary nividia module, which COULD
have something to do with this, but it's hard to say for sure.
Nevertheless, to avoid this division by zero, we should check that
stepsize is defined. If stepsize is not defined, print an error and
bail out on the tune request.
V4L/DVB (10164): Add missing S2 caps flag to S2API
The attached patch adds a capability flag that allows an application
to determine whether a particular device can handle "second generation
modulation" transponders. This is necessary in order for applications
to be able to decide which device to use for a given channel in
a multi device environment, where DVB-S and DVB-S2 devices are mixed.
It is assumed that a device capable of handling "second generation
modulation" can implicitly handle "first generation modulation".
The flag is not named anything with DVBS2 in order to allow its
use with future DVBT2 devices as well (should they ever come).
