The MTK xHCI controller use some reserved bytes in endpoint context for bandwidth scheduling, so need keep them in xhci_endpoint_copy(); The issue is introduced by: commitf5249461b5("xhci: Clear the host side toggle manually when endpoint is soft reset") It resets endpoints and will drop bandwidth scheduling parameters used by interrupt or isochronous endpoints on MTK xHCI controller.

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.
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.
