reiserfs: audit transaction ids to always be unsigned ints
This patch fixes up the reiserfs code such that transaction ids are
always unsigned ints. In places they can currently be signed ints or
unsigned longs.
The former just causes an annoying clm-2200 warning and may join a
transaction when it should wait.
The latter is just for correctness since the disk format uses a 32-bit
transaction id. There aren't any runtime problems that result from it
not wrapping at the correct location since the value is truncated
correctly even on big endian systems. The 0 value might make it to
disk, but the mount-time checks will bump it to 10 itself.

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.

V4L/DVB (11248): Remove debug output from stb6100_cfg.h
This patch removes the debug output from stb6100_cfg.h as it is flooding

V4L/DVB (11236): tda827x: fix locking issues with DVB-C
Separate tuning table for DVB-C solves tuning problem at 388MHz
TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.
This is suggested by the name of the table: tda827xa_dvbt.
Added a table for DVB-C with the name tda827xa_dvbc.
Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.
This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c
The tda827x.c gives the following warning message when debug=1:
tda827x: tda827x_config not defined, cannot set LNA gain!
Solved this by adding a tda827x_config struct in budget-ci.c.
