[qemu/hw/pci/pcie.c:148] -> [qemu/hw/pci/pcie.c:148]: (style) Same expression on both sides of '|'. pci_long_test_and_set_mask(dev->w1cmask + pos + PCI_EXP_DEVSTA, PCI_EXP_DEVSTA_CED | PCI_EXP_DEVSTA_NFED | PCI_EXP_DEVSTA_URD | PCI_EXP_DEVSTA_URD); I am guessing that something like pci_long_test_and_set_mask(dev->w1cmask + pos + PCI_EXP_DEVSTA, PCI_EXP_DEVSTA_CED | PCI_EXP_DEVSTA_NFED | PCI_EXP_DEVSTA_FED | PCI_EXP_DEVSTA_URD); was intended. I used static analyser cppcheck to find this bug. Fixed here: http://git.qemu.org/?p=qemu.git;a=commitdiff;h=8e815eeefe205155f5
