[PATCH 5/9] iommu/ipmmu-vmsa: Make it explicitly non-modular
From: Paul Gortmaker
Date: Sat Dec 01 2018 - 14:22:06 EST
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.
