The function mipi_dsi_device_transfer() returns the number of transmitted or received bytes on success or a negative error code on failure. The functions mipi_dsi_shutdown_peripheral(), mipi_dsi_turn_on_peripheral() & mipi_dsi_set_maximum_return_packet_size() use improperly this returned value in case of success: 0 should be returned instead of the number of transmitted bytes.

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.
