reliably. Every so often depending on the phase of the moon and your

wrong.  The addresses are always set to -1, but because it's an unsigned 8-bit
value, the left shift converts it to the nonsense address 0x1fe.

In the cx8802 driver, some cut and pasted code prefixed lines with "CORE
cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from

- It compiles to be smaller and faster, without needing the extra array lookup

- The boards array can be made const

- It should be possible to avoid keeping the (large) cx88_boards array around

V4L/DVB (5997): cx25840: fix audio mute handling and reporting

Audio muting for the tuner input was implemented by stopping the
audio microcontroller and restarting it on unmute. However, it
appears that this method can actually crash the audio firmware.
It's rare and seems to happen with NTSC only.

It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.

V4L/DVB (5978): tuner: Better tuner radio support

Add radio support for the Thomson DTT7612 tuner.

This tuner uses a different 1st intermediate frequency than the other radio
tuners supported (a lot of NTSC radio tuners probably need this change too).

Add a new tuner-simple parameter, radio_if.  It selects the 1st IF used for
radio reception.  The radio frequency setting code in tuner-simple now uses
this field, instead of a special case select() block for each tuner with radio
support.

The tuner parameters for tuners that used a 33.3 MHz RIF now set radio_if to 1
in tuner-types.c.

The Thomson DTT7612 gets radio_if = 2, also add has_tda9887 = 1 and
fm_gain_normal = 1.

Add some defines for tda9887 bits that control IF setting in radio mode.

Add a new tda9887 config option, TDA9887_RIF_41_3, that selects a 41.3 MHz
radio IF.

Fix the way tda9887 radio options work.  The driver was modifying the default
radio mode config templates based on the TDA9887_XXXX flags.  This means that
_all_ tuners would get the same settings.  If you had a one tuner than used
TDA9887_GAIN_NORMAL and one that didn't, both would get the setting.  Now the
tda9987 driver just checks if tuner mode is radio and then applies the config
settings directly to the data being sent, just like how all the TV mode
settings already work.

The PLL setting math is made a little more accurate.

V4L/DVB (5884): zr36067: clean up debug function

Debugging cleanups to the zr36067 driver:

* Use module_param_named() to declare the debug parameter, so we can
  use a single global variable to handle the debug level. This makes
  the driver a bit smaller (by 648 bytes on x86_64), thanks to one
  less level of indirection on every use.

* Change the debug parameter sysfs permissions, so that the debug
  level can be adjusted at runtime, as is done in many other
  media/video drivers.

* The debug level is between 0 and 5, not 0 and 4.

* Move the zr_debug export and dprintk macro definition to a header
  file so that we don't have to define them in each source file.

* Simplify a duplicate test on zr_debug.

Note that zr_debug was subsequently renamed to debug_zr36067 to avoid
possible conflicts with other Zoran device drivers, on a suggestion
by Trent Piepho.
