[PATCH 9/9] PCI: hotplug: make PCIe core code explicitly non-modular

From: Paul Gortmaker
Date: Wed Aug 24 2016 - 16:58:36 EST

The Makefile fragments currently controlling compilation of this code are:

obj-$(CONFIG_HOTPLUG_PCI_PCIE) += pciehp.o
pciehp-objs := pciehp_core.o \

The Kconfig currently controlling compilation of this code is:

drivers/pci/pcie/Kconfig:config HOTPLUG_PCI_PCIE
drivers/pci/pcie/Kconfig: bool "PCI Express Hotplug driver"

...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.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit. However
one could argue that we should use subsys_initcall() here, but for
now we stick with runtime equivalence.

We delete module.h but we keep the moduleparam.h include, since we are
keeping the module_param() that the file has as-is for now.

We also delete the MODULE_LICENSE tag etc since all that information
is still contained higher up in the file via the DEFINE lines which
now serve as documentation only.
