Subject: [PATCH v2 3/4] usb: dwc2: Fix dr_mode check in dwc2_get_dr_mode
Date: Thu, 10 Dec 2020 11:31:03 +0100	[thread overview]
Message-ID: <20201210103104.3816-3-jmaselbas@kalray.eu> (raw)
In-Reply-To: <20201210103104.3816-1-jmaselbas@kalray.eu>

In Linux, configs CONFIG_USB_DWC2_HOST and CONFIG_USB_DWC2_GADGET
are respectively for host only and gadget only support, they are
mutually exclusive. However this is not the case in barebox, they
are independent options.
