Re: [PATCH 1/2] fpga: dfl: pci: reduce the scope of variable 'ret'

[Tom Rix]

Please check the scope.

On linus/master, the result of this change looks like

static int cci_pci_sriov_configure(struct pci_dev *pcidev, int num_vfs)
{
    struct cci_drvdata *drvdata = pci_get_drvdata(pcidev);
    struct dfl_fpga_cdev *cdev = drvdata->cdev;

    if (!num_vfs) {
        /*
         * disable SRIOV and then put released ports back to default
         * PF access mode.
         */
        pci_disable_sriov(pcidev);

        dfl_fpga_cdev_config_ports_pf(cdev);

    } else {
        int ret; <--- defined here

        /*
         * before enable SRIOV, put released ports into VF access mode
         * first of all.
         */
        ret = dfl_fpga_cdev_config_ports_vf(cdev, num_vfs);
        if (ret)
            return ret;

        ret = pci_enable_sriov(pcidev, num_vfs);
        if (ret)
            dfl_fpga_cdev_config_ports_pf(cdev);
    }

    return ret;  <---- not in scope, not defined here
}
