Subject: [PATCH] usb: cdns3: Fixed incorrect gadget state
Date: Wed, 23 Jun 2021 09:02:47 +0200	[thread overview]
Message-ID: <20210623070247.46151-1-pawell@gli-login.cadence.com> (raw)

From: Pawel Laszczak <pawell@cadence.com>

For delayed status phase, the usb_gadget->state was set
to USB_STATE_ADDRESS and it has never been updated to
USB_STATE_CONFIGURED.
Patch updates the gadget state to correct USB_STATE_CONFIGURED.
As a result of this bug the controller was not able to enter to
Test Mode while using MSC function.
