Hello Antti,

Thank you for the patch. Problem solved.

I checked with both versions 3.42.3.3 and 3.39.1.0 of
dvb-usb-it9135-02.fw. With 3.39.1.0 I usually get some blocks when
zapping (they disappear after a short while when staying on the same
channel). With 3.42.3.3 I don't have this issue. Looks like 3.42.3.3 is
an improvement.

Kind regards,
Sebastian
