Subject[PATCH] PCI: xilinx: Fix return value in case of error
Date
In function 'xilinx_pcie_init_irq_domain', the pattern used to check and
return error is:

if (!var) {
dev_err(...);
return PTR_ERR(var);
}

So the returned value in case of error is always 0, which means 'success'.
Change it to return -ENODEV instead.
