The driver-specific usage of the DMA_CTRL_ACK flag was replaced with a custom flag in commit ceeeb99cd821 ("dmaengine: mxs: rename custom flag"), but i2c-mxs was not updated to use the new flag, completely breaking I2C transactions using DMA.

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.
