Commit cd221bd24ff5 ("iommu/arm-smmu: Allow building as a module")
introduced a side effect that changed the module name from arm-smmu to
arm-smmu-mod. This breaks the users of kernel parameters for the driver
(e.g. arm-smmu.disable_bypass). This patch changes the module name back
to be consistent.

Can't we just override MODULE_PARAM_PREFIX instead of renaming the file?

I can do that. But on the other hand, the "mod" in the module name
arm-smmu-mod.ko seems to be redundant and looks a little bit weird.
Wouldn't it be cleaner to make it just arm-smmu.ko?

Leo

I just didn't fancy renaming the file because it's a pain for backports
and why does the name of the module matter?
