Timur: you do compile test your patches, right? :-P

I have a script that tests each commit in a set to make sure it compiles, 
so that git-bisect isn't broken.

This doesn't make any sense.  If you change fsl_diu_info into a pointer, 
then where is the object being allocated?

Tomorrow, when I get into the office, I'll take a look.  But my code has 
always compiled.  Can you give me the output of your compiler?

I prefer this:

	disable_lcdc(data->fsl_diu_info);

Your change makes sense.  I don't understand why it compiles on my system. 
  Something strange is going on.

I figured out what the problem is.  I never compiled a configuration with
CONFIG_PM enabled.  For some reason, CONFIG_PM is disabled when SMP is
enabled, and I only tested with mpc85xx_smp_defconfig.

Florian,

I've not seen this appear in mainline as yet.  

When do you expect to send a pull request?
