[PATCH] uml: mmapper - remove just added but wrong "const" attribute
When enabling the mmapper driver I got warnings because this "const" miscdevice structure is passed to function as non-const pointer; unlike struct tty_operations, however, I verified that misc_{de,}register _do_ modify their parameter, so this const attribute must be removed. Since the purpose of the change was to guarantee that no lock was needed, add a comment to prove this differently.
