Olivier Dautricourt d3ddfab096 dmaengine: altera-msgdma: cleanup after completing all descriptors
msgdma_chan_desc_cleanup iterates the done list for each completed
descriptor while we need to do it once after all descriptors are
completed.

This fixes a Sparse warning because we first take the lock in
msgdma_tasklet.
- Move locking to msgdma_chan_desc_cleanup.
- Move call to msgdma_chan_desc_cleanup outside of the critical section of
msgdma_tasklet.

Inspired by: commit 16ed0ef3e9 ("dmaengine: zynqmp_dma: cleanup after
                                   completing all descriptors")

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 reStructuredText 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.
