ARM: simplify __iounmap() when dealing with section based mapping
Firstly, there is no need to have a double pointer here as we're only walking the vmlist and not modifying it. Secondly, for the same reason, we don't need a write lock but only a read lock here, since the lock only protects the coherency of the list nothing else. Lastly, the reason for holding a lock is not what the comment says, so let's remove that misleading piece of information. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>
