DMA_ERROR_CODE already isn't a valid API to user for drivers and will go away soon. exynos_drm_fb_dma_addr uses it a an error return when the passed in index is invalid, but the callers never check for it but instead pass the address straight to the hardware. Add a WARN_ON instead and just return 0. Signed-off-by: Christoph Hellwig <hch@lst.de> |

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
