When handing the SETUP packet by composite_setup(), we will release the dwc->lock. If we get the 'USB_GADGET_DELAYED_STATUS' result from setup function, which means we need to delay handling the STATUS phase. But during the lock release period, maybe the request for handling delay STATUS phase has been queued into list before we set 'dwc->delayed_status' flag or entering 'EP0_STATUS_PHASE' phase, then we will miss the chance to handle the STATUS phase. Thus we should check if the request for delay STATUS phase has been enqueued when entering 'EP0_STATUS_PHASE' phase in dwc3_ep0_xfernotready(), if so, we should handle it.

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.
