[libvirt] [PATCH 1/6] pci: Remove redundant parameter from virPCIDeviceBindToStub()

This internal function supports, in theory, binding to a different stub driver than the one the PCI device has been configured to use. In practice, it is only ever called like virPCIDeviceBindToStub(dev, dev->stubDriver); which makes its second parameter redundant. Get rid of it, along with the extra string copy required to support it. --- src/util/virpci.c | 17 +++++------------ 1 file changed, 5 insertions(+), 12 deletions(-) diff --git a/src/util/virpci.c b/src/util/virpci.c index 6f0cb8c..424983d 100644 --- a/src/util/virpci.c +++ b/src/util/virpci.c @@ -1177,20 +1177,18 @@ virPCIDeviceUnbindFromStub(virPCIDevicePtr dev) static int -virPCIDeviceBindToStub(virPCIDevicePtr dev, - const char *stubDriverName) +virPCIDeviceBindToStub(virPCIDevicePtr dev) { int result = -1; bool reprobe = false; char *stubDriverPath = NULL; char *driverLink = NULL; char *path = NULL; /* reused for different purposes */ - char *newDriverName = NULL; + char *stubDriverName = dev->stubDriver; virErrorPtr err = NULL; if (!(stubDriverPath = virPCIDriverDir(stubDriverName)) || - !(driverLink = virPCIFile(dev->name, "driver")) || - VIR_STRDUP(newDriverName, stubDriverName) < 0) + !(driverLink = virPCIFile(dev->name, "driver"))) goto cleanup; if (virFileExists(driverLink)) { @@ -1305,13 +1303,8 @@ virPCIDeviceBindToStub(virPCIDevicePtr dev, VIR_FREE(driverLink); VIR_FREE(path); - if (result < 0) { - VIR_FREE(newDriverName); + if (result < 0) virPCIDeviceUnbindFromStub(dev); - } else { - VIR_FREE(dev->stubDriver); - dev->stubDriver = newDriverName; - } if (err) virSetError(err); @@ -1354,7 +1347,7 @@ virPCIDeviceDetach(virPCIDevicePtr dev, return -1; } - if (virPCIDeviceBindToStub(dev, dev->stubDriver) < 0) + if (virPCIDeviceBindToStub(dev) < 0) return -1; /* Add *a copy of* the dev into list inactiveDevs, if -- 2.5.0
