#1734859 — [PATCH] Fix for hanging si2168 in PCTV 292e, making the code match

[re-sending as plain text]

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.

(Patch basis Linux 4.11.9 f82a53b87594f460f2dd9983eeb851a5840e8df8)
