[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.
