The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_WM8350_I2C drivers/mfd/Kconfig: bool "Wolfson Microelectronics WM8350 with I2C" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. We don't replace module.h with init.h since the file already has that. But we do delete an unused moduleparam.h Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
