vchan_vdesc_fini() shouldn't be called under a spin_lock. This is done in two places, once in vchan_terminate_vdesc() and once in vchan_synchronize(). Instead of freeing the vdesc right away, collect the aborted vdescs on a separate list and free them along with the other vdescs. The terminated descs are also freed in vchan_synchronize as done before this patch.

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.
