mainlining shenanigans

In sdma_tx_status() we must first find the current sdma_desc. In cyclic mode we assume that this can always be found with vchan_find_desc(). This is true because do not remove the current descriptor from the desc_issued list: /* * Do not delete the node in desc_issued list in cyclic mode, otherwise * the desc allocated will never be freed in vchan_dma_desc_free_list */ if (!(sdmac->flags & IMX_DMA_SG_LOOP)) list_del(&vd->node); We will change this in the next step, so check if the current descriptor is the desired one also for the cyclic case.

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.
