You didn't do anything with Yinghai's comment. He's 100% correct: you have to add the put_device() that corresponds to the new get_device() calls you're adding. Both have to be in the same patch. > Signed-off-by: Gu Zheng <guz.fnst@cn.fujitsu.com> > --- > arch/powerpc/kernel/pci_of_scan.c | 3 +-- > drivers/char/agp/alpha-agp.c | 2 +- > drivers/char/agp/parisc-agp.c | 2 +- > drivers/pci/iov.c | 2 +- > drivers/pci/probe.c | 3 +-- > drivers/scsi/megaraid.c | 2 +- > 6 files changed, 6 insertions(+), 8 deletions(-) > > diff --git a/arch/powerpc/kernel/pci_of_scan.c b/arch/powerpc/kernel/pci_of_scan.c > index 2a67e9b..24d01c4 100644 > --- a/arch/powerpc/kernel/pci_of_scan.c > +++ b/arch/powerpc/kernel/pci_of_scan.c > @@ -128,7 +128,7 @@ struct pci_dev *of_create_pci_dev(struct device_node *node, > const char *type; > struct pci_slot *slot; > > - dev = alloc_pci_dev(); > + dev = pci_alloc_dev(bus); > if (!dev) > return NULL; > type = of_get_property(node, "device_type", NULL); > @@ -137,7 +137,6 @@ struct pci_dev *of_create_pci_dev(struct device_node *node, > > pr_debug(" create device, devfn: %x, type: %s\n", devfn, type); > > - dev->bus = bus; > dev->dev.of_node = of_node_get(node); > dev->dev.parent = bus->bridge; > dev->dev.bus = &pci_bus_type; > diff --git a/drivers/char/agp/alpha-agp.c b/drivers/char/agp/alpha-agp.c > index dd84af4..199b8e9 100644 > --- a/drivers/char/agp/alpha-agp.c > +++ b/drivers/char/agp/alpha-agp.c > @@ -174,7 +174,7 @@ alpha_core_agp_setup(void) > /* > * Build a fake pci_dev struct > */ > - pdev = alloc_pci_dev(); > + pdev = pci_alloc_dev(NULL); > if (!pdev) > return -ENOMEM; > pdev->vendor = 0xffff; > diff --git a/drivers/char/agp/parisc-agp.c b/drivers/char/agp/parisc-agp.c > index 94821ab..bf5d247 100644 > --- a/drivers/char/agp/parisc-agp.c > +++ b/drivers/char/agp/parisc-agp.c > @@ -333,7 +333,7 @@ parisc_agp_setup(void __iomem *ioc_hpa, void __iomem *lba_hpa) > struct agp_bridge_data *bridge; > int error = 0; > > - fake_bridge_dev = alloc_pci_dev(); > + fake_bridge_dev = pci_alloc_dev(NULL); > if (!fake_bridge_dev) { > error = -ENOMEM; > goto fail; > diff --git a/drivers/pci/iov.c b/drivers/pci/iov.c > index ee599f2..dba2031 100644 > --- a/drivers/pci/iov.c > +++ b/drivers/pci/iov.c > @@ -76,7 +76,7 @@ static int virtfn_add(struct pci_dev *dev, int id, int reset) > struct resource *res; > struct pci_sriov *iov = dev->sriov; > > - virtfn = alloc_pci_dev(); > + virtfn = pci_alloc_dev(NULL); > if (!virtfn) > return -ENOMEM; > > diff --git a/drivers/pci/probe.c b/drivers/pci/probe.c > index 5233fb6..59637a6 100644 > --- a/drivers/pci/probe.c > +++ b/drivers/pci/probe.c > @@ -1280,11 +1280,10 @@ static struct pci_dev *pci_scan_device(struct pci_bus *bus, int devfn) > if (!pci_bus_read_dev_vendor_id(bus, devfn, &l, 60*1000)) > return NULL; > > - dev = alloc_pci_dev(); > + dev = pci_alloc_dev(bus); > if (!dev) > return NULL; > > - dev->bus = bus; > dev->devfn = devfn; > dev->vendor = l & 0xffff; > dev->device = (l >> 16) & 0xffff; > diff --git a/drivers/scsi/megaraid.c b/drivers/scsi/megaraid.c > index 9504ec0..e1660ca 100644 > --- a/drivers/scsi/megaraid.c > +++ b/drivers/scsi/megaraid.c > @@ -2025,7 +2025,7 @@ megaraid_abort_and_reset(adapter_t *adapter, Scsi_Cmnd *cmd, int aor) > static inline int > make_local_pdev(adapter_t *adapter, struct pci_dev **pdev) > { > - *pdev = alloc_pci_dev(); > + *pdev = pci_alloc_dev(NULL); > > if( *pdev == NULL ) return -1; > > -- > 1.7.1 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-pci" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hi Bjorn, Thanks for your reminder, Yinghai's comment is completely right, the get_device()/put_device() should come in pairs. I'll add the put_device() in the next version.
