Subject: [PATCH] musb: sunxi: Ignore VBus errors in host-only mode
Date: Tue, 4 Aug 2015 23:25:53 +0200 [thread overview]
Message-ID: <1438723553-4136-1-git-send-email-hdegoede@redhat.com> (raw)
For some unclear reason sometimes we get VBus errors in host-only mode,
even though we do not have any vbus-detection then. Ignore these.
