CC [M]  drivers/isdn/sc/shmem.o
drivers/isdn/sc/shmem.c: In function ‘memcpy_toshmem’:
drivers/isdn/sc/shmem.c:53: warning: passing argument 1 of ‘memcpy_toio’ makes pointer from integer without a cast

Commit 9317d4313e:

	ISDN/sc: fix longstanding warning

claimed to fix it, but it didn't.

[ Changed the "void *" to be "void __iomem *" -DaveM ]
