That would make it look more like other similar information we print elsewhere. When you're debugging a problem, sometimes you have to compare address information from different places, and it's convenient if they all look similar. > mvebu_pcie_del_windows(port, base - size_mapped, > size_mapped); > return; > -- > 1.8.3.2 > -- 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

Understood your point, but in order to use %pR we need to use a 'struct resource', which is something that the current code is not using. 'sz' is calculated inside the function, so it is helpful to print it as is. IMHO if %pR should be used to improve readability, then it should be handled via a separate patch. This one does not introduce any functional change. -- 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

I suggested using a similar printk format, e.g., "[mem %#010llx-%#010llx]". -- 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

Thanks for the clarification.
