[PATCH] PCI: xilinx: Fix return value in case of error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
