Subject: usb: host: xhci-plat: propagate return value of platform_get_irq()
X-Git-Tag: microblaze-4.13-rc1~51^2~3
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=4b148d5144d64ee135b8924350cb0b3a7fd21150;p=linux-2.6-microblaze.git

usb: host: xhci-plat: propagate return value of platform_get_irq()

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.
