[PATCH] iommu/ipmmu-vmsa: Remove ipmmu_utlb_disable()

From: Joerg Roedel
Date: Fri Jan 13 2023 - 13:57:03 EST


From: Joerg Roedel <jroedel@xxxxxxx>

The function is unused after commit 1b932ceddd19 ("iommu:
Remove detach_dev callbacks") and so compilation fails with

drivers/iommu/ipmmu-vmsa.c:305:13: error: ‘ipmmu_utlb_disable’ defined but not used [-Werror=unused-function]
305 | static void ipmmu_utlb_disable(struct ipmmu_vmsa_domain *domain,
| ^~~~~~~~~~~~~~~~~~

Remove the function to fix the compile error.

Fixes: 1b932ceddd19 ("iommu: Remove detach_dev callbacks")
