commitafc92514a3upstream. If the "workaround_for_vbus" is true, the driver will not call usb_disconnect(). So, since the controller keeps some registers' value, the driver doesn't re-enumarate suitable speed after the b-device mode is disabled. To fix the issue, this patch adds usb_disconnect() calling in renesas_usb3_b_device_write() if workaround_for_vbus is true.

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.
