Fix for hanging si2168 in PCTV 292e USB, making the code match the comment.
Using firmware v4.0.11 the 292e would work once and then hang on
subsequent attempts to view DVB channels, until physically unplugged and
plugged back in.
With this patch, the warm state is reset for v4.0.11 and it appears to
work both on the first attempt and on subsequent attempts.
It is comment which is wrong. With firmware 4.0.11 it works well without
need of download it every time. But firmware 4.0.19 needs to be
downloaded every time after device is put to sleep.
Probably your issue is coming from some other reason.
