Doesn't look like a regression to me. Doubled timeout looks like a
problem with timer. I'll follow up on the original thread.

Not really a regression. Alan seems to have a general fix and I think
we can also quirk the specific case.

Possible fix proposed.

I'll push the fix once Paul verifies it.

Thanks.

Fixed in my tree not a regression. I'll try and push some bits monday
this included.

I was traveling abroad last week, without access to my devel
environment. Hans is currently working on a definitive fix for the
issue. His schedule is to have a proper solution until next week.

For now, it is better just to revert the bad changes. I've committed a
patch on my tree for that:

http://git.kernel.org/?p=linux/kernel/git/mchehab/v4l-dvb.git;a=commitdiff;h=15ac2d293b08b6975c6ca1a80eb839d4cb0dddbf

I'm currently running some tests on my environment with the fix patches
I currently have. I should send a pull request to Linus later today.
