[ Upstream commit61ae7f8694] __iomem attribute is supposed to be used only with variables holding the MMIO pointer. But here, 'mw_addr' variable is just holding a 'void *' returned by pci_epf_alloc_space(). So annotating it with __iomem is clearly wrong. Hence, drop the attribute. This also fixes the below sparse warning: drivers/pci/endpoint/functions/pci-epf-vntb.c:524:17: warning: incorrect type in assignment (different address spaces) drivers/pci/endpoint/functions/pci-epf-vntb.c:524:17: expected void [noderef] __iomem *mw_addr drivers/pci/endpoint/functions/pci-epf-vntb.c:524:17: got void * drivers/pci/endpoint/functions/pci-epf-vntb.c:530:21: warning: incorrect type in assignment (different address spaces) drivers/pci/endpoint/functions/pci-epf-vntb.c:530:21: expected unsigned int [usertype] *epf_db drivers/pci/endpoint/functions/pci-epf-vntb.c:530:21: got void [noderef] __iomem *mw_addr drivers/pci/endpoint/functions/pci-epf-vntb.c:542:38: warning: incorrect type in argument 2 (different address spaces) drivers/pci/endpoint/functions/pci-epf-vntb.c:542:38: expected void *addr drivers/pci/endpoint/functions/pci-epf-vntb.c:542:38: got void [noderef] __iomem *mw_addr Fixes:e35f56bb03("PCI: endpoint: Support NTB transfer between RC and EP") Signed-off-by: Manivannan Sadhasivam <mani@kernel.org> Reviewed-by: Frank Li <Frank.Li@nxp.com> Link: https://patch.msgid.link/20250709125022.22524-1-mani@kernel.org Signed-off-by: Sasha Levin <sashal@kernel.org>
