[media] video: Drop undue references to i2c-algo-bit
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.

V4L/DVB (12343): Stop defining I2C adapter IDs nobody uses
There is no point in defining I2C adapter IDs when no code is using
them. As this field might go away in the future, stop using it when
we don't need to.

V4L/DVB (11343): au0828: make i2c clock speed per-board configurable
Setup the i2c clock speed to be definable on a per-board basis. This allows
us to explicitly set the clock speed to 30 KHz on the 950q, and also gets rid
of code which sets it on a basis of what chip the i2c master is talking to
at any given time (which could have caused issues because i2c slaves should
never receive commands at a clock higher than their supported clock speed).

V4L/DVB (11074): au0828: fix i2c enumeration bug
There was a bug where enumerating the i2c for devices would result in false
positives. The root of the issue was the scanning was using SMBUS_QUICK
messages, which are zero length write requests (which our i2c adapter
implementation didn't handle). Because we never strobed any bytes onto the
bus, the status register would still contain the value from the previous
request.

V4L/DVB (11067): au0828: workaround a bug in the au0828 i2c handling
There is an issue related to the i2c clock for addressing the xc5000. The
au0828 chip does not support clock stretching, which the xc5000 makes use of.
This results in cases where we silently get back garbage in i2c read
operations. To work around this issue until we slow down the i2c clock when
talking with that specific device.
This was not an issue before we had analog support because we never needed to
enumerate the i2c bus, and digital tuning never actually needed to perform
read operations against the xc5000.

<stoth@linuxtv.org> for providing sample hardware, engineering level support,

V4L/DVB (7750): au0828/ cleanups and fixes
This patch contains the following cleanups and fixes:
- "debug" is definitely not a good name for a global variable,
renamed it to "au0828_debug"
this fixes a compile error with some kernel configurations
- since the module parameter is int the variable shouldn't be unsigned
- remove the {usb,bridge,i2c}_debug module parameters since they are
already covered by the "debug" module parameter
- remove the unused au0828_bcount
- make the needlessly global i2c_scan static
- make the needlessly global dvb_register() static
