There are numerous issues in error handling code of cx231xx initialization.
Double free (when cx231xx_init_dev() calls kfree(dev) via cx231xx_release_resources()
and then cx231xx_usb_probe() does the same) and memory leaks
(e.g. usb_get_dev() before (ifnum != 1) check in cx231xx_usb_probe())
are just a few of them.
The patch fixes the issues in cx231xx_usb_probe() and cx231xx_init_dev()
by moving usb_get_dev(interface_to_usbdev(interface)) below in code and
implementing proper error handling.

Thanks for the response, I have done as you suggested.
Below is an updated patch for the OTG102 device against http://git.linuxtv.org/hverkuil/media_tree.git/shortlog/refs/heads/cx231xx, kernel version 3.8.
With further testing it appears the extra clauses in cx231xx-cards.c were not necessary (in static in cx231xx_init_dev and static int cx231xx_usb_probe), so those have been also been removed.

The 417 support doesn't work. Until someone can dig into this driver to
figure out why it isn't working the 417 support is disabled.
Sometimes you can actually stream a bit, but very soon the whole machine
crashes, so something is seriously wrong.
For the record, this was not introduced by my recent changes to this driver,
it was broken before that.

Instead of using 3.3 MHz IF, use 4MHz. That's the standard
value for the demod, and, while it can be adjusted, 3.3 MHz
is out of the recommended range. So, let's stick with the
default.
With regards to the IF voltage level, instead of using
0.5 V(p-p) for IF, use 2V, giving a 12dB gain.
The rationale is that, on PixelView SBTVD Hybrid,
even 2V(p-p) would be in the nominal range for IF,
as the maximum range on this particular device is 3V.
A higher gain here should help to improve reception under
weak signals.
