commit f035d139ffece7b6a7b8bfb17bd0ba715ee57a04 upstream. DWC3 tracks TRB counter for each ep0 direction separately. In control read transfer completion handler, the driver needs to reset the TRB enqueue counter for ep0 IN direction. Currently the driver only resets the TRB counter for control OUT endpoint. Check for the data direction and properly reset the TRB counter from correct control endpoint.

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.
