[ Upstream commit af3f606e0bbb6d811c50b7b90fe324b07fb7cab8 ]
The field pcie_reg_base in struct mobiveil_pcie represents a physical address so it should be of phys_addr_t type rather than void __iomem*; this results in the following compilation warnings:
drivers/pci/controller/pcie-mobiveil.c: In function 'mobiveil_pcie_parse_dt': drivers/pci/controller/pcie-mobiveil.c:326:22: warning: assignment makes pointer from integer without a cast [-Wint-conversion] pcie->pcie_reg_base = res->start; ^ drivers/pci/controller/pcie-mobiveil.c: In function 'mobiveil_pcie_enable_msi': drivers/pci/controller/pcie-mobiveil.c:485:25: warning: initialization makes integer from pointer without a cast [-Wint-conversion] phys_addr_t msg_addr = pcie->pcie_reg_base; ^~~~ drivers/pci/controller/pcie-mobiveil.c: In function 'mobiveil_compose_msi_msg': drivers/pci/controller/pcie-mobiveil.c:640:21: warning: initialization makes integer from pointer without a cast [-Wint-conversion] phys_addr_t addr = pcie->pcie_reg_base + (data->hwirq * sizeof(int));
Fix the type and with it the compilation warnings.
