The OF functionality has moved to a common place and be used by many
archs. So we don't need to depend on PPC_OF option any more. This is
a preparation for killing PPC_OF.
I suspect that you want to do the PPC_OF -> PPC conversion on this file
rather than just removing PPC_OF uses.
That was my first thought, but the codes protected by the PPC_OF seem not
ppc specific and should be safe for other archs which also support OF. So I
drop the PPC_OF completely. Did I miss something?

I see no way in this file for struct device_node to be defined
(especially if CONFIG_PPC is not set).  of.h may be included
implicitly, but that is very dependent on the architecture and CONFIG_
options.
This do pass the build test for the non-OF archs, such as x86. But your
concerns sound pretty reasonable, so I will explicitly include of.h.

This will emit the above error if CONFIG_OF is not set whereas in the
past it would not.
How about change it to:
	if (IS_ENABLED(CONFIG_OF))
  		printk(KERN_ERR "imsttfb: no OF node for pci device\n");

Thanks,
Kevin
