[PATCH 3.16 058/233] usb: host: xhci-plat: propagate return value of platform_get_irq()

[Ben Hutchings]

3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Petazzoni <thomas.petazzoni@xxxxxxxxxxxxxxxxxx>

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.
