From 4be85fc4f8eabd0b265e1f891fe0e733bf01407a Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sat, 29 Oct 2016 21:24:35 -0400 Subject: mfd: ab3100-core: Make it explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config AB3100_CORE drivers/mfd/Kconfig: bool "ST-Ericsson AB3100 Mixed Signal Circuit core functions" ...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. In doing so, the debugfs unregister fcn becomes unused so we remove it too. 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. 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.
