SubjectRe: [RESEND v4 1/6] misc: Add Synopsys DesignWare xData IP driver
[+cc Bjorn]

Hi Gustavo,

Thank you!

There might be one more change, and improvement, to be done as per
Bjorn's feedback, see:

The code in question would be (exceprt from the patch):

+static int dw_xdata_pcie_probe(struct pci_dev *pdev,
+ const struct pci_device_id *pid)
+ const struct dw_xdata_pcie_data *pdata = (void *)pid->driver_data;
+ struct dw_xdata *dw;
+ dw->rg_region.vaddr = pcim_iomap_table(pdev)[pdata->rg_bar];
+ if (!dw->rg_region.vaddr)
+ return -ENOMEM;

Perhaps something like the following would would?

void __iomem * const *iomap_table;

iomap_table = pcim_iomap_table(pdev);
if (!iomap_table)
return -ENOMEM;

dw->rg_region.vaddr = iomap_table[pdata->rg_bar];
if (!dw->rg_region.vaddr)
return -ENOMEM;

With sensible error messages added, of course. What do you think?
