When digitizing composite video from a analog videotape source using the
TVP5150's first composite input channel, the captured stream exhibits
tearing and synchronization problems[1].
It turns out that commit c0477ad9fe caused
"TV mode" (as opposed to "VCR mode" or "auto-detect") to be forcibly
enabled for both composite inputs. According to the chip
documentation[2], "TV mode" disables a "chrominance trap" input filter,
which appears to be necessary for high-quality video capture from an
analog videotape source. [ Commit
c7c0b34c27 subsequently restricted the
problem to the first composite input, apparently inadvertently. ]
Since any type of composite signal source can be connected to the
TVP5150's first composite input, unconditionally forcing "TV mode" isn't
correct. There doesn't appear to be a good way for applications to tell
the driver what is connected. Fortunately, the TVP5150 has an operating
mode auto-detection feature, which, when enabled, should cause the TVP5150
to auto-detect whether it should use "VCR mode" or "TV mode". Enabling
operating mode auto-detection improved video capture quality
significantly[3].
Therefore, fix this bug by using operating mode auto-detection. (Also,
while here, fix a CodingStyle issue.)
For those users who may find this patch via a mailing list archive but who
are not able to upgrade to a kernel with a fixed driver: the TVP5150's
S-Video and second composite input sources have auto-detection enabled, so
you may wish to try using those -- if available on your device -- until
this fix makes it a downstream distribution near you.

Thank you Sami very much!
The biggest bug I fixed is that,
I was clobbering the CIRCFG register after it is setup
That wasn't a good idea really
And some small refactoring, etc.

The driver was missing KERN_ facilities on a number of printks. The
register dump functions have been updated to use KERN_INFO, so that the
register dump gets logged in syslog (they only run on driver load, and
only when debug is enabled). The buffer dump routine now uses
KERN_DEBUG, as that spew will happen quite frequently (several times
every IR signal), and shouldn't need to be logged.
Also split up the small handful of lines that were just over 80
characaters, and fixed the ioctl.h include.

As soon as input device is registered, it might be accessed (and it is)
This can trigger a hardware interrupt that can access
not yet initialized ir->raw, (by sending a sample)
This can be reproduced by holding down a remote button and reloading the module.
And this always crashes the systems where hardware decides to send an interrupt
right at the moment it is enabled.
