Hi Mauro, Jean,
When converting the bttv driver to v4l2_subdev I found one probing conflict
between tvaudio and ir-kbd-i2c: address 0x96 (or 0x4b in 7-bit notation).
It turns out that this is one and the same PIC16C54 device used on

Hi Mauro, Jean,

It turns out that this is one and the same PIC16C54 device used on the

Actually, it seems like this used to work at one time in the past. Jean, can
