Do you understand that code at all?
No I can't really say I understand all the workings of the media api.
Now it is:
FE0 == (fe->id == 0) == RTL2832
FE1 == (fe->id == 1) == MN88472
you changed it to:
FE0 == (fe->id == 0) == MN88472
FE1 == (fe->id == 1) == RTL2832
I thought the rtl2832u_frontend_attach() actually attached the devices.
Then the id's would have followed the frontend.
Then there is:
/* bypass slave demod TS through master demod */
if (fe->id == 1 && onoff) {
ret = rtl2832_enable_external_ts_if(adap->fe[1]);
if (ret)
goto err;
}
After your change that code branch is taken when RTL2832 demod is
activated / used. Shouldn't TS bypass enabled just opposite, when
MN88472 is used....

This intent of the patch was for better backwards compatibility with old
software. This isn't strictly needed so consider the patch dropped.
I just tested that patch, and it behaves just like I expected - does not
work at all (because RTL2832 TS bypass will not be enabled anymore).
Here is log, first with your patch, then I fixed it a little as diff
shows, and after that scan works. I wonder what kind of test you did for
it - or do you have some other hacks committed...
