The current descriptor is not on any list of the virtual DMA channel. Once sdma_terminate_all() is called when a descriptor is currently in flight then this one is forgotten to be freed. We have to call vchan_terminate_vdesc() on this descriptor to re-add it to the lists. Now that we also free the currently running descriptor we can (and actually have to) remove the current descriptor from its list also for the cyclic case.

README
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.
