These days TUNER_SET_CONFIG is broadcast to the other i2c devices
and that triggers a fw load on the cx25840. Ignore this command
since cx25840 isn't a tuner and you really do not want to load
the firmware that early.

Move radio->muted and radio->stereo in section where radio mutex is
locked to avoid possible race condition problems or access to memory.

=======================
The culprit in the trace is snd_pcm_action() which invokes a spin lock
which disables pre-emption which disables an IRQ which causes the
__might_sleep() function to fail the irqs_disabled() test. Since
pre-emption is enabled then it is safe to de-allocate the memory if
you first unlink each URB. In this instance you are safe since
pre-emption is disabled. If pre-emption and irqs are not disabled then
call usb_kill_urb(), else call usb_unlink_urb().
Thanks to Douglas for tracking down this bug originally!!!

at ffffffff" boundary="------------060402040603020802080803"
From: Tony Broad <tony@byteworkshop.co.uk>
I'm using a "Hauppauge WinTV-NOVA-T DVB card" of PCI id "13c2:1005" with
kernel 2.6.27.9.
I've recently experienced the following fairly consistent kernel oops on
startup in grundig_29504_401_tuner_set_params from budget.c. As you
might expect, following this failure, the card doesn't work.
I'm not a kernel developer, nevertheless I seem to have managed to track
this down to a non-existent initialisation of
budget->dvb_frontend->tuner_priv.
The attached patch fixes the problem for me (and I've managed to tune
the card successfully as a result), but I don't know of anyone else
using the driver so I can't test it on other people.
Please let me know if this works for you or if I've done something
terribly wrong ;-(

From: Mike Isely <isely@pobox.com>
The name of the pvrusb2 module is not likely to ever change, and there
are plenty of other places where the name is directly coded, so there
is little utility in using a macro to infer the module name here. In
addition, using that macro complicates other uses of the driver
involving older kernels where this macro works differently. Yes I
know for many places we don't have to worry about that. But my
alternative is that I have to build special logic in the pvrusb2
standalone driver to special-case what is otherwise costmetic and that
is just plain nuts for something as trivial as this, especially since
this change does not at all have any compile time or run time impact
on the driver. I'm just removing a nicety that didn't have a lot of
value here to begin with.

It appears that various v4l-dvb drivers are changing to require
explicit initialization before use. This change to the pvrusb2 driver
implements an automatic issuance of VIDIOC_INT_INIT when a module is
bound to the driver, thus conforming to the new behavior.

With the conversion to v4l2_subdev one bit of code was accidentally dropped:
on receiving the first command the driver has to load the fw. A new init()
command was introduced to do that explicitly for bridge drivers that are
converted to use v4l2_subdev, but old drivers that are not yet converted
no longer worked.
This patch fixes this regression for these old drivers.

The VIDIOC_QUERYCTRL command needs to actually do a queryctrl, not a
querymenu. Similarly, the VIDIOC_QUERYMENU command needs to actually
do a querymenu not a queryctrl.

Previous v4l-dvb changeset id 4cc8ed11e2e0 changed the pvrusb2-hdw
internal API regarding i2c chip debug register access. However that
change failed to also update the corresponding function comment
describing the API. As driver maintained I never saw a request for an
ack on that change; there probably should have been one especially
since the manner in which this API operates was changed - its
interface is now entangled with a v4l specific struct and I would have
preferred to keep this API clear of moving-target v4l-isms such as
this one if at all possible which is why I had done it the way I did
before. But whatever. This commit at least fixes the comment issue.

Use the new pvrusb2 internal API to grab the device identifier, rather
than generating it directly. This unifies some code and make possible
use of that identifier in places other than sysfs.

Implement a new internal function to create a string device
identifier. This ID stays with the specific device, making it useful
to user space to identify specific devices. We use the serial number
if available; otherwise we give up and just spit out a unit/instance ID.
