Hi.
IMO, your thoughts about core resource locking mechanism sound good.
I say here some thoughts and examples how the resource locking mechanism might
work.
IMHO, It's good enough now if we are heading to a solution.
At least I would not alone find a proper concept.

Hi.
I think that you could reuse lots of code with smart suspend / resume.
What do you think about this DVB power saving case (about the concept, don't
look at details, please):
- One device has responsibility to do the power off when it can be done
(mantis_core.ko)
- In my case there is only

The tuner core puts the chip into standby when the last V4L filehandle
is closed. Yes, I realize this violates the V4L spec since you should

Anything with an xc3028 or xc5000 would have this issue. I don't
really keep close track of cur

An xc2028/xc3028 should be fine, as that does support standby.

Second version of this patch series.
It's the same as RFCv1, except that I dropped the g_frequency and
g_tuner/s_tuner patches (patch 3, 6 and 7 in the original patch series)
because I need to think more on those, and I added a new fix for tuner_resume
which was broken as well.
