Kernel warning from Matrox Framebuffer in 2.6.20.1

Kernel warning from Matrox Framebuffer in 2.6.20.1

[Chris Rankin]

Hi,

I have just booted 2.6.20.1 on my Pentium 3 machine, which has a G400 MAX graphics card. This
machine uses the Matrox framebuffer and TV-OUT modules, and I have found these warnings in the
kernel log:

**WARNING** I2C adapter driver [DDC:fb0 #0] forgot to specify physical device; fix it!
**WARNING** I2C adapter driver [DDC:fb0 #1] forgot to specify physical device; fix it!
**WARNING** I2C adapter driver [MAVEN:fb0] forgot to specify physical device; fix it!

The relevant kernel modules seem to be:

matroxfb_maven         13228  0
i2c_matroxfb            4064  0
i2c_algo_bit            6312  1 i2c_matroxfb

Cheers,
Chris

I'm seeing something like that since installing 2.6.20.1 yesterday:

matroxfb: Matrox Mystique (PCI) detected
PInS memtype = 0
matroxfb: MTRR's turned on
matroxfb: 1024x768x8bpp (virtual: 1024x4096)
matroxfb: framebuffer at 0xE1000000, mapped to 0xcc880000, size 4194304
Console: switching to colour frame buffer device 128x48
fb0: MATROX frame buffer device
**WARNING** I2C adapter driver [DDC:fb0 #0] forgot to specify physical device; 
fix it!

Can you try current git tree?  I believe that it is already fixed by 
Jean Delvare checkin from Feb 13th (thanks Jean!)
