Linux kernel source tree

No matter what type of event we receive we want to increase the event ring dequeue pointer one step for every event that is handled. For unknown reasons the event ring dequeue increase is done inside the transfer event handler and port event handler. As the transfer event handler got more complex and can now loop through several transfer TRBs on a transfer ring, there were additinal checks added to avoid increasing event ring dequeue more than one step. No need for elaborate checks to avoid increasing event ring dequeue in case the transfer event handler goes through a loop. Just increasing the event ring dequeue outside the transfer event handler. End goal is to increase event ring dequeue in just one place.

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.
