I looked into this last week and I'm pretty confident this is just a
bogus version test. If you look at the lines near the errors
mentioned, you'll see a check for kernel 2.6.13; however, struct class
didn't gain .dev_attrs, and hadn't renamed .release to .dev_release,
until 2.6.19.
If you change both #if LINUX_VERSION_CODE lines from 13 to 19 you'll
get it to compile (with a warning), but there will be another error
v4l1-compat.c that I'm not entirely sure of how to handle. At least on
my system it chokes on the __pure attribute to palette_to_pixelformat().
The patch I used to get the latest v4l-dvb to compile is appended. It
seems to work for me but I can't guarantee its correctness, YMMV, etc.

I used this patch and managed to get the modules to compile and load
on my 2.6.18 debian/etch kernel. However, I have a question. Will
these modules now load in a deterministic manner? For instance,
on this box I have a PVR-150, a air2PC card, an Avermedia A180,
and a DVICO pcHDTV RT5 lite. My issue is that in myth, I need to
assign the proper /dev/device to the proper capture device.
To get around that with previous versions, I had some custom rules in
hotplug/udev that would create custom aliases, such as /dev/ivtv0,
/dev/bttv_vid0. However, this release has broken the mechanism that
created my /dev/ivtv0, so mythtv isn't happy.
Will all devices load and create /dev/video* in the same order all the time,
or is it still up in the air as to which device will create which
/dev/video*, based upon who's faster today????
This is a long outstanding issue with udev/hotplug, but someone needs to
fix it, if they can figure out how.
