4.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
commit 4b148d5144d64ee135b8924350cb0b3a7fd21150 upstream.
platform_get_irq() returns an error code, but the xhci-plat driver ignores it and always returns -ENODEV. This is not correct, and prevents -EPROBE_DEFER from being propagated properly.
