Previously if we run out of TRBs for the last SG entry that requires an extra TRB, we set interrupt-on-completion (IOC) bit to an already prepared TRB (i.e. HWO=1). This logic is not clean, and it's not a typical way to prepare TRB. Also, this prevents showing IOC setup in tracepoint when __dwc3_prepare_one_trb() is executed. Instead, let's look ahead when preparing TRB to know whether to set the IOC bit before the last SG entry. This requires adding a new parameter "must_interrupt" to dwc3_prepare_one_trb().

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.
