+Subject: usb: gadget: core: fix ->udc_set_speed() logic
+
+From: Roger Quadros <rogerq@ti.com>
+
+commit 97e133d54c1ca8948b191e5721a145a76c4db33d upstream.
+
+Consider the following case: udc controller supports SuperSpeed.  If we
+first load a HighSpeed gadget followed by a SuperSpeed gadget, the
+SuperSpeed gadget will be limited to HighSpeed as UDC core driver
+doesn't call ->udc_set_speed() in the second case.
+
+Call ->udc_set_speed() unconditionally to fix this issue.
+
+This will also fix the case for dwc3 controller driver when SuperSpeed
+gadget is loaded first and works in HighSpeed only as udc_set_speed()
+was never being called.
+
+Fixes: 6099eca796ae ("usb: gadget: core: introduce ->udc_set_speed() method")
