commit d9193efba84fe4c4aa22a569fade5e6ca971f8af upstream. Observed "TRB completion code (27)" error which corresponds to Stopped - Length Invalid error(xhci spec section 4.17.4) while connecting USB to SATA bridge. Looks like this case was not considered when the following patch[1] was committed. Hence adding this new check which can prevent the invalid byte size error.

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.
