A call to irq_find_matching_host was already made and the result
has been stored in mc_msi_domain. mc_msi_domain is again reassigned
using the same function call which is redundant.

irq_find_matching_host returns/locates a domain for a given fwnode.
The domain is identified using device node and bus_token(if several
domains have same device node but different purposes they can be
distinguished using bus-specific token).
http://www.bricktou.com/include/linux/irqdomain_irq_find_matching_host_en.html

Also, of_property_read_bool finds and reads a boolean from a property
device node from which the property value is to be read. It doesn't
alter the device node.
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-February/083698.html

Since, both  the function calls have the same device node and bus_token,
the return values shall be the same. Hence, the second call has been
removed.

There is a use-after-free problem in the ion driver.
This is caused by a race condition in the ion_ioctl()
function.

A handle has ref count of 1 and two tasks on different
cpus calls ION_IOC_FREE simultaneously.

cpu 0                                   cpu 1
-------------------------------------------------------
ion_handle_get_by_id()
(ref == 2)
                            ion_handle_get_by_id()
                            (ref == 3)

ion_free()
(ref == 2)

ion_handle_put()
(ref == 1)

                            ion_free()
                            (ref == 0 so ion_handle_destroy() is
                            called
                            and the handle is freed.)

                            ion_handle_put() is called and it
                            decreases the slub's next free pointer

The problem is detected as an unaligned access in the
spin lock functions since it uses load exclusive
 instruction. In some cases it corrupts the slub's
free pointer which causes a mis-aligned access to the
next free pointer.(kmalloc returns a pointer like
ffffc0745b4580aa). And it causes lots of other
hard-to-debug problems.

This symptom is caused since the first member in the
ion_handle structure is the reference count and the
ion driver decrements the reference after it has been
freed.

To fix this problem client->lock mutex is extended
to protect all the codes that uses the handle.
