For devices not instantiated through ACPI the i2c-client's device-name gets set to <busnr>-<addr> by default, e.g. "0-0022" this means that the device-name is dependent on the order in which the i2c-busses are enumerated. In some cases having a predictable constant device-name is desirable, for example on non device-tree platforms the link between a regulator and its consumers is specified by the platform code by setting regulator_init_data.consumers. This array identifies the regulator's consumers by dev_name and supply(-name). Which requires a constant dev_name. This commit adds a dev_name field to i2c_board_info allowing platform code to set a contstant dev_name so that the device can be identified by its dev_name in other platform code.

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.
