Subject: PCI: mobiveil: Integer overflow in IB_WIN_SIZE
Git-commit: 014562071c96524b518d4d3513fcde072c8e63b5
Patch-mainline: v4.19-rc1
References: fate#326572
IB_WIN_SIZE is larger than INT_MAX so we need to cast it to u64.
Fixes: 9af6bcb11e12 ("PCI: mobiveil: Add Mobiveil PCIe Host Bridge IP driver")
