The hibernation code is broken and has never been enabled in mainline and should thus be dropped. Specifically, the scratch buffer DMA mapping would have been leaked on every suspend cycle since commit51f5d49ad6("usb: dwc3: core: simplify suspend/resume operations") if this feature was ever enabled. The related error handling was also broken and could have resulted in attempts to unmap never mapped buffers, etc. This effectively revert commit0ffcaf3798("usb: dwc3: core: allocate scratch buffers").

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.
