The bttv driver has code to detect if a tda9887 is present, that was previous
used to auto-load the tda9887 driver. Now there is no tda9887 driver, so the
code is pointless; it just figures out if it should load the driver and then
does nothing.
For cards that are defined as having no tuner, the init code would still do
i2c probes for various tuner devices and auto-load the tuner module. That can
be skipped for cards that don't need it. The code is made to understand that
in addition to 'UNSET', 'TUNER_ABSENT' also means no tuner.
The tuner into printk()s are also made nicer. Levels are added, INFO or
WARNING, depending on the meaning. For cards with no tuner, or no tuner
defined, a more informative message is printed.
Card has no tuner, before patch:
bttv0: tuner type=-1
or
bttv0: tuner type=4
After patch:
bttv0: tuner absent
Card has a tuner, but the type isn't defined, before patch:
bttv0: tuner type=-1
After patch:
bttv0: tuner type unset [<- also warning now, as the tuner won't work right]

The last user of dvb_pll_configure was the dvb-usb function
dvb_usb_tuner_calc_regs(), which was nothing more than a wrapper around
dvb_pll_configure(). It's just a copy of the functionality provided by
the tuner_ops calc_regs method, and can be deleted.
There were two users of dvb_usb_tuner_calc_regs().
One was dvb_usb_tuner_set_params_i2c(), which is converted to use
fe->ops.tuner_ops.calc_regs().
The other was the digitv driver. This driver can use one of two demods,
mt352 or nxt6000.
For the mt352, the driver would set tuner_ops.calc_regs to
dvb_usb_tuner_calc_regs().
We can just attach dvb_pll and use the tuner_ops.calc_regs() provided by
that module. For the nxt600, the driver would set tuner_ops.set_params
to digitv_nxt6000_tuner_set_params.
That function would in turn use dvb_usb_tuner_calc_regs().
We convert it to use tuner_ops.calc_regs() instead, and use
dvb_pll_attach.
The digitv_tuner_attach() needs to know which frontend was attached by
digitv_frontend_attach(), since the nxt6000 needs tuner_ops.set_params()
to be overridden with digitv_nxt6000_tuner_set_params().
So, to do this a digitv_state that says which frontend was used is added
to the dvb_usb_device private state field.

Sound recording doesn't work for this card because ACNI and ACPF
are not set before snd_card_saa7134_capture_prepare(). As a result
timeout occurs. These registers aren't poked because thread
never gets wake up signal. ACNI initialization is done in the
thread.
Sound is muted when capture stops. Shouldn't be because it may

Although it is safe to kfree(NULL), We only need to kfree(priv)
if the release callback is undefined. As it stands now, there
is some redundancy in the operation of releasing the priv data
structures. This patch will call kfree(priv) and set priv to NULL,
if the release callback isnt defined. Otherwise, let the release
callback handle this itself.
