We had a 100us delay to synchronize the END_TRANSFER command completion before giving back requests to the function drivers. Now, the controller driver can handle cancelled TRBs with the requests' cancelled_list and it can also wait until the END_TRANSFER completion before starting new transfers. Synchronization can simply base on the controller's command completion interrupt. The 100us delay is no longer needed. Remove this arbitrary delay.

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.
