From 31cbae2224c189b54a198ba4c9e93fea30ed61f1 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sat, 29 Oct 2016 21:24:36 -0400 Subject: mfd: ab8500-core: Make it explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config AB8500_CORE drivers/mfd/Kconfig: bool "ST-Ericsson AB8500 Mixed Signal Power Management chip" ...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 replace module.h with moduleparam.h ; the latter since this file was implicitly relying on getting it. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
