dmaengine_terminate_all() is deprecated. When converting the existing calls, it turned out that the termination in the DMA setup and callback were superfluous and only a side effect of simply calling rcar_i2c_cleanup_dma(). As either no DMA transfers have been submitted yet or the last one has successfully completed, there is nothing to terminate and we can leave it out. So, merge the DMA unmap and cleanup function to save some code. Then, add a flag if the new cleanup function needs to terminate DMA. This is only the case for the erorr handling in the main thread, so we can finally switch from dmaengine_terminate_all() to dmaengine_terminate_sync() here.

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.
