In some cases device sending ZLP IN on non EP0 which reassigning EP0 OUT descriptor pointer to that EP. Dedicated for EP0 OUT descriptor multiple time re-used by other EP while that descriptor already in use by EP0 OUT for SETUP transaction. As result when SETUP packet received BNA interrupt asserting. In dwc2_hsotg_program_zlp() function dwc2_gadget_set_ep0_desc_chain() must be called only for EP0.

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.
