commitba3a80fe0fupstream. It should use the correct direction value from register, not depends on previous software setting. It fixed the EP number wrong issue at trace when the TRBERR interrupt occurs for EP0IN. When the EP0IN IOC has finished, software prepares the setup packet request, the expected direction is OUT, but at that time, the TRBERR for EP0IN may occur since it is DMULT mode, the DMA does not stop until TRBERR has met.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
