Subject: [PATCH 8/8] usb: host: xhci-plat: propagate return value of platform_get_irq()
Date: Wed, 17 May 2017 18:32:06 +0300 [thread overview]
Message-ID: <1495035126-29091-9-git-send-email-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <1495035126-29091-1-git-send-email-mathias.nyman@linux.intel.com>
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
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.
