I looked those just through and I want more information about every
patch. Mainly I want to know which resolves which problem. As far as I
understand, there is two problems;
1. register access fails sometimes (as I suspect in case of access some
registers when firmware is programming tuner or doing some other task
and does not expect it is interrupted)
2. stream corruptions
Is that possible you identify which changes fix 1 and what are for 2?
I fixed that I2C failing, simply blocking problematic demod callbacks
that only other demod can access at once. Basically problem is that
AF9015 FW don't like to get interrupted for I2C access in certain cases.

That was easy to guess after I2C mux approach didn't fixed errors

If someone would like to see how that new mux can be used, take a look here:

I haven't looked stream corruptions and I will not even look, since
those not happening much my hw. I think your fix is based the fact you
forced PID-filter always on. Could you remove all the other changes you
did and force it using dvb-usb orce_pid_filter_usage param to see if
thats really the only only problem? And also testing using max packet
sizes could be interesting to see.
I will now continue implement get_if() for AF9013 and tuners it uses.
