[patch] remove unnessesary casts from drivers/mtd/maps/nettel.c and kill two warnings

[Jesper Juhl]

I took a look at the cause for these warnings in the 2.6.10 kernel,

drivers/mtd/maps/nettel.c:361: warning: assignment makes pointer from integer without a cast
drivers/mtd/maps/nettel.c:395: warning: assignment makes pointer from integer without a cast

and as far as I can see the casts in there (to unsigned long and back to 
void*) are completely unnessesary ('virt' in 'struct map_info' is a void 
__iomem *), and getting rid of those casts buys us a warning free build.

Are there any reasons not to apply the patch below?
Unfortunately I don't have hardware to test this patch, so it has been 
compile tested only.

Please keep me on CC since I'm not subscribed to linux-mtd.
