Subject: iommu/ipmmu-vmsa: Make it explicitly non-modular
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8128ac3b0fe316d4bbedae54068ac24a623c08b5;p=linux.git

iommu/ipmmu-vmsa: Make it explicitly non-modular

The Kconfig currently controlling compilation of this code is:

drivers/iommu/Kconfig:config IPMMU_VMSA
drivers/iommu/Kconfig:        bool "Renesas VMSA-compatible IPMMU"

...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 was not even used by this driver, the init ordering
remains unchanged with this commit.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
