commit 1cf44baad76b6f20f95ece397c6f643320aa44c9

IO resources: fix/remove printk
Andrew Morton noticed that the printk in kernel/resource.c was buggy:
| start and end have type resource_size_t. Such types CANNOT be printed
| unless cast to a known type.
|
| Because there is a %s following an incorrect %lld, the above code will
| crash the machine.
... and it's probably quite unneeded as well, so remove it.
