From mboxrd@z Thu Jan 1 00:00:00 1970 From: hdegoede@redhat.com (Hans de Goede) Date: Tue, 4 Aug 2015 23:25:53 +0200 Subject: [PATCH] musb: sunxi: Ignore VBus errors in host-only mode Message-ID: <1438723553-4136-1-git-send-email-hdegoede@redhat.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
