Subject: [PATCH 3/4] usb: dwc2: Fix mode check in dwc2_get_dr_mode
Date: Wed, 9 Dec 2020 15:55:46 +0100 [thread overview]
Message-ID: <20201209145547.22655-3-jmaselbas@kalray.eu> (raw)
In-Reply-To: <20201209145547.22655-1-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.
