From: Jean-Jacques Hiblot <jjhiblot@xxxxxxxxxxxxxxx>
This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 4f4bde1df33bde076f53325bdf2c6430cf85e1bb upstream.
The second parameter of of_read_number() is not the index, but a size. As
it happens, in this case it may work just fine because of the conversion to
u32 and the favorable endianness on this architecture.
Fixes: 11be65472a427 ("PCI: mvebu: Adapt to the new device tree layout")
