3.18-stable review patch. If anyone has any objections, please let me know.

From: Thomas Petazzoni <thomas.petazz...@bootlin.com>
[ Upstream commit dfd0309fd7b30a5baffaf47b2fccb88b46d64d69 ]
pcie->realio.end should be the address of last byte of the area,
therefore using resource_size() of another resource is not correct, we
must substract 1 to get the address of the last byte.
