Subject: [PATCH v1 06/10] ehci-atmel: Power down during suspend is normal
Date: Fri, 8 Sep 2017 17:36:00 +0200 [thread overview]
Message-ID: <20170908153604.28383-7-romain.izard.pro@gmail.com> (raw)
In-Reply-To: <20170908153604.28383-1-romain.izard.pro@gmail.com>
When an Atmel SoC is suspended with the backup mode, the USB bus will be
powered down. As this is expected, do not return an error to the driver
core when ehci_resume detects it.
