[devsk]

Mike,

Would you be pushing these into 2.6.30.1?

Thanks,
devsk

>       VBI is now initialized in the cx25840 driver only after the chip
>       has been initialized (fixes 24xxx) and again after any time the

>   (+) Instantiate ir_video I2C device by default - basically change
>       the default value of the "disable_autoload_ir_video" option to
>       zero.
