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.
