Subject[PATCH] 2.5.5-pre1 fix build error in drivers/video/vesafb.c
Date
Hello all,

This patch is some hackery-quackery to fix a problem with drivers/video/vesafb.c.

I got the following error building 2.5.5-pre1. I also had this error with 2.5.4-preX,
but after seeing the discussions relating to bus_to_virt etc., I hoped that a
real fix would appear.

drivers/video/video.o: In function `vesafb_init':
drivers/video/video.o(.text.init+0x154b): undefined reference to `bus_to_virt_not_defined_use_pci_map'
make: *** [vmlinux] Error 1

Quoting Andrew Morton in his recent interview with kerneltrap.org,
"One hot tip: if you spot a bug which is being ignored, send a completely botched fix
to the mailing list. This causes thousands of kernel developers to rally to the cause.
Nobody knows why this happens. (I really have deliberately done this several times. It works)."

Well this bug is certainly not being ignored, but here is my completely botched fix.

Cheers,
Steven
