| Subject: [PATCH] iommu: amd: hide unused iommu_table_lock |
| |
| The newly introduced lock is only used when CONFIG_IRQ_REMAP is enabled: |
| |
| drivers/iommu/amd_iommu.c:86:24: error: 'iommu_table_lock' defined but not used [-Werror=unused-variable] |
| static DEFINE_SPINLOCK(iommu_table_lock); |
| |
| This moves the definition next to the user, within the #ifdef protected |
| section of the file. |
| |
| Fixes: ea6166f4b83e ("iommu/amd: Split irq_lookup_table out of the amd_iommu_devtable_lock") |
