fsl_ep_queue() is only called by usb_ep_queue() (as ep->ops->queue()). So _ep isn't NULL. As ep->ops->queue = fsl_ep_queue, the ep was initialized by struct_ep_setup() and so ep->udc isn't NULL either. Drop the check for _ep being NULL and assign udc earlier to prevent following an uninitialized pointer in the two dev_vdbg()s in lines 878 and 882. This fixes a compiler warning when using clang and CONFIG_USB_GADGET_VERBOSE=y.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. 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.
