Description:   Opened: 2007-02-22 15:37 0000 
The 2.6.20 kernel included a bug in the cx25840 module that prevents it from
being able to load it's firmware. Attached is a patch I received from the IVTV
driver author, who is part of the v4l2 group.

This isn't merged upstream and also isn't merged in the v4l subsystem tree.

Please provide the name/email of the patch author, and a description of the
problem you saw before this patch, so that I can submit it upstream.

Also, in future, it helps me if the patches you post can be applied with -p1
from the root of the kernel sources directory. Thanks.

Upstream author is Hans Verkuil, hverkuil@xs4all.nl.  The details are in the
README of ivtv-0.10.0 release.

"NOTE: This driver will work with kernels 2.6.18, 2.6.19 and 2.6.20. For the
latter kernel you will need to apply the cx25840.diff patch that is in the
'misc' directory (only if your card has the cx2584x chip, it is not needed
otherwise). The 2.6.20 kernel caused a cx2584x bug to surface that prevents
loading of the cx2584x firmware."
