Subject: [PATCH] PCI: switchtec: Add missing __iomem tag to fix sparse warnings
Git-commit: 42dae8937406c98ce0cb6ff0d683765c854098d9
Patch-mainline: v5.9-rc1
References: git-fixes
Fix a missing __iomem tag in the init_pfn() function. This fixes a sparse
warning of the form:
$ make C=2 drivers/pci/switch/
drivers/pci/switch/switchtec.c:... incorrect type assignment(different address spaces)
Fixes: 080b47def5e5 ("MicroSemi Switchtec management interface driver")
