[PATCH] iommu/arm-smmu: fix the module name for disable_bypass parameter

From: Li Yang
Date: Tue Feb 11 2020 - 18:37:41 EST


Since commit cd221bd24ff5 ("iommu/arm-smmu: Allow building as a module"),
there is a side effect that the module name is changed from arm-smmu to
arm-smmu-mod. So the kernel parameter for disable_bypass need to be
changed too. Fix the Kconfig help and error message to the correct
parameter name.
