Previously, one would set the mfd_cell's platform_data/data_size to point to the current mfd_cell in order to pass that information along to drivers. This causes the current mfd_cell to always be available to drivers. It also adds a wrapper function for fetching the mfd cell from a platform device, similar to what originally existed for mfd devices. Drivers who previously used platform_data for other purposes can still use it; the difference is that mfd_get_data() must be used to access it (and the pdata structure is no longer allocated in mfd_add_devices). Note that mfd_get_data is intentionally vague (in name) about where the data is stored; variable name changes can come later without having to touch brazillions of drivers.
