There's one comment that has been copied from bttv to many other
media/video drivers:

/* init + register i2c algo-bit adapter */

Meanwhile, many drivers use hardware I2C implementations instead of
relying on i2c-algo-bit, so this comment is misleading. Remove the
reference to "algo-bit" from all drivers, to avoid any confusion. This
is the best way to ensure that the comments won't go out of sync
again. Anyone interested in the implementation details would rather
look at the code itself.

were guarded by bttv_debug tests.

Add pr_fmt.
Convert printks to pr_<level>
Convert printks without KERN_<level> to appropriate pr_<level>.
Removed embedded prefixes when pr_fmt was added.
Whitespace cleanups when around other conversions.
Macros coded with if statements should be do { if... } while (0)
so the macros can be used in other if tests.
Use ##__VA_ARGS__ for variadic macro as well.
Coalesce format strings.

Move I2C IR initialization from just after I2C bus setup to right
before non-I2C IR initialization. This avoids the case where an I2C IR
device is blocking audio support (at least the PV951 suffers from
this). It is also more logical to group IR support together,
regardless of the connectivity.

There are old bttv-driven Hauppauge WinTV series cards that have
their IR part at i2c addr 0x71, which doesn't get considered in the
new 2.6.31 i2c code.

From a 2.6.29 kernel:

lirc_i2c: chip 0x10005 found @ 0x71 (Hauppauge PVR150)

Minor cosmetic glitch, the card in question isn't actually a PVR-150, its:

03:06.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
Subsystem: Hauppauge computer works Inc. WinTV Series
Flags: bus master, medium devsel, latency 32, IRQ 19
Memory at f4ffe000 (32-bit, prefetchable) [size=4K]
Capabilities: [44] Vital Product Data
Capabilities: [4c] Power Management version 2
Kernel driver in use: bttv
Kernel modules: bttv

Device ID: 0x109e:0x036e, Sub-Device ID: 0x0070:0x13eb

This simply adds 0x71 to the list of addresses i2c_new_probed_device should
consider, which gets IR working on this card again.

Let card drivers probe for IR receiver devices and instantiate them if
found. Ultimately it would be better if we could stop probing
completely, but I suspect this won't be possible for all card types.

There's certainly room for cleanups. For example, some drivers are
sharing I2C adapter IDs, so they also had to share the list of I2C
addresses being probed for an IR receiver. Now that each driver
explicitly says which addresses should be probed, maybe some addresses
can be dropped from some drivers.

Also, the special cases in saa7134-i2c should probably be handled on a
per-board basis. This would be more efficient and less risky than always
probing extra addresses on all boards. I'll give it a try later.

Since i2c autoprobing will disappear bttv needs to be converted to use
v4l2_subdev instead.

Without autoprobing the autoload module option has become obsolete. A warning
is generated if it is set, but it is otherwise ignored.

Since the bttv card definitions are of questionable value a new option was
introduced to allow the user to control which audio module is selected:
msp3400, tda7432 or tvaudio (or none at all).

By default bttv will use the card definitions and fallback on tvaudio as the
last resort.

If no audio device was found a warning is printed.

The saa6588 RDS device is now also explicitly probed since it is no longer
possible to autoprobe it. A new saa6588 module option was added to override
the card definition since I suspect more cards have this device than one
would guess from the card definitions.

Note that the probe addresses of the i2c modules are hardcoded in this
driver. Once all v4l drivers are converted to v4l2_subdev this will be
cleaned up. Such data belongs in an i2c driver header.

The bttv card database structure had a "tuner" field that was the input
number of the tuner input or UNSET for no tuner. However, the only values
it could ever be are 0 and UNSET. Having a tuner on an input other than 0
didn't work and was never used.

There is also a "tuner_type" field that can be set to TUNER_ABSENT to
indicate no tuner, which makes "tuner = UNSET" redundant. In many cases,
tuner_type was set to UNSET when there was no tuner, which isn't quite
correct. tuner_type == UNSET is supposed to mean the tuner type isn't yet
known.

So, I changed cards where "tuner == UNSET" to always have tuner_type of
TUNER_ABSENT. At this point the tuner field is redundant, so I deleted it.

I have the card setup code set the card's tuner_type (not the card type's
tuner_type!) to TUNER_ABSENT if it hasn't yet been set at the end of the
setup code. Various places that check if the card has a tuner will now
look for this instead of checking the card type's "tuner" field.

Also autoload the tuner module before issuing the TUNER_SET_TYPE_ADDR I2C
client call instead of after issuing it.

Overall, on ia32 this decreases compiled code size by about 24 bytes and
reduces the data size by 640 bytes.

Clean up the use of structure templates in bttv-i2c. For one thing, a
real template is supposed to be read-only. And in some cases it's more
efficient to initialize the few fields we need individually.

Software I2C were using a very conservative value of udelay=16, meaning about
20Kbps. According with Philips I2C datasheet, the i2c should answer well for
times at the order of 4.7 us. So, using udelay=5 should work for all devices.
After this patch, the speed should be close to 66,67 Kbps, with the current
kernel software bitbang, with 30/60 duty cycle.
Anyway, added a new parameter (i2c_udelay) that would allow using conservative
values, if eventually a hardware doesn't support the datasheet values.
Thanks to Jean Delvare <khali@linux-fr.org> for pointing this improvement.

Cleanup audio input handling in bttv and tvaudio:
- inputs were specified that were never used
- mute was handled as a special input which led to confusing code
- confusing naming made it difficult to see if the setting was for
i2c or gpio.
The old audiochip.h input names moved to tvaudio.h. Currently this
is used both by tvaudio and msp3400 until the msp3400 implements the
new msp3400-specific inputs.
Detect in bttv the tvaudio and msp3400 i2c clients and use these
client pointers to set the inputs directly instead of broadcasting the
command.
Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be
replaced again later by the new ROUTING commands.
Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is
a user level command and not to be used internally. It wasn't called at
all anyway.
