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")

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
