In the following test we get stuck by sleeping forever in _dwc3_set_mode() after which dual-role switching doesn't work. On dra7-evm's dual-role port, - Load g_zero gadget driver and enumerate to host - suspend to mem - disconnect USB cable to host and connect otg cable with Pen drive in it. - resume system - we sleep indefinitely in _dwc3_set_mode due to. dwc3_gadget_exit()->usb_del_gadget_udc()->udc_stop()-> dwc3_gadget_stop()->wait_event_lock_irq() To fix this instead of waiting indefinitely with wait_event_lock_irq() we use wait_event_interruptible_lock_irq_timeout() and print and error message if there was a timeout.

README
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.
