From 57b51b9adb4ca67d15c4f4b61268771da014c44a Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Wed, 24 Aug 2016 16:57:51 -0400 Subject: PCI: hotplug: Make core explicitly non-modular This code is not being built as a module by anyone: obj-$(CONFIG_HOTPLUG_PCI) += pci_hotplug.o [...] pci_hotplug-objs := pci_hotplug_core.o drivers/pci/hotplug/Kconfig:menuconfig HOTPLUG_PCI drivers/pci/hotplug/Kconfig: bool "Support for PCI Hotplug" Remove uses of MODULE_DESCRIPTION(), MODULE_AUTHOR(), MODULE_LICENSE(), etc., so that when reading the driver there is no doubt it is builtin-only. The information is preserved in comments at the top of the file. Remove orphaned exit function in cpci_hotplug_core.c. Note that for non-modular code, module_init() translates to device_initcall(). One could argue that we should use subsys_initcall() here, but for now we stick with runtime equivalence. We would delete module.h and just keep the moduleparam.h include (since the file does use module_param), but there is a try_module_get and module_put pairing that prevents us from doing that.
