[PATCH -next] iommu/msm: Make msm_iommu_lock static

[Samuel Zou]

Fix the following sparse warning:

drivers/iommu/msm_iommu.c:37:1: warning: symbol 'msm_iommu_lock' was not declared.

The msm_iommu_lock has only call site within msm_iommu.c
It should be static

Fixes: 0720d1f052dc ("msm: Add MSM IOMMU support")
