1b750d09fe [media] mxl5005s: fix: don't discard bandwidth changes
There is a bug on mxl5005s logic: when the bandwidth changes, but using
the same delivery system, the code discard the set_params()
reconfiguration request.

This was happening because, in the previous coding, the bandwidth
calculus were after the check for delivery system changes.

The previous patch changed the logic to estimate the bandwidth to
happend together with the changes at the delivery system.

So, with a one-statement change, it is possible to make the tuner to
reconfigure, in order to adjust to bandwidth changes. this will
likely fix issues on countries that use 7MHz/8MHz DVB-T channels.

0607d07780 [media] dvb_core: estimate bw for all non-terrestial systems
Instead of just estimating the bandwidth for DVB-C annex A/C,
also fill it at the core for ATSC and DVB-C annex B. This
simplifies the logic inside the tuners, as all non-satellite
tuners can just use c->bandwidth_hz for all supported
delivery systems.

It could make sense to latter use it also for satellite
systems, as several DVB-S drivers have their own calculus.
However, on DVB-S2 the bw estimation is a little more complex,
and the existing drivers have some optimized calculus for
bandwidth. So, let's not touch on it for now.

b037c0fde2 [media] media: vb2: fix potential deadlock in mmap vs. get_userptr handling
To get direct access to userspace memory pages vb2 allocator needs to
gather read access on mmap semaphore in the current process.
The same semaphore is taken before calling mmap operation, while
both mmap and qbuf are called by the driver or v4l2 core with
driver's lock held. To avoid a AB-BA deadlock (mmap_sem then
driver's lock in mmap and driver's lock then mmap_sem in qbuf)
the videobuf2 core release driver's lock, takes mmap_sem and then
takes again driver's lock. get_userptr methods are now called with
all needed locks already taken to avoid further lock magic inside
memory allocator's code.
