  [PATCH 09/10] drivers/pci: make host/pci-keystone.c explicitly non-modular Paul Gortmaker <paul.gortmaker@windriver.com> - 2015-12-13 02:50 +0100

#1290530 — [PATCH 09/10] drivers/pci: make host/pci-keystone.c explicitly non-modular

The Kconfig currently controlling compilation of this code is:

drivers/pci/host/Kconfig:config PCI_KEYSTONE
drivers/pci/host/Kconfig:       bool "TI Keystone PCIe controller"

...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_platform_driver() uses the same init level priority as
builtin_platform_driver() 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.
