Regarding this, I would like to open up a discussion here. This "instance_id" actually is used for registering the mdio bus as a bus id. The original code use "1" for the bus id. If the system plug in more than one stmmac pci cards, I believe there is conflict on the mdio bus registration. So introduce this static global variable is to increase the bus id starting from "1" base on how many stmmac pci cards being plugged in. So, to change the "instance_id" by using some identifier, the only thing come to my mind is pci_dev->devfn number. Is anyone have concern about using devfn number as an mdio bus id ? > > + plat_dat->mdio_bus_data = devm_kzalloc(&pdev->dev, > > + sizeof(*plat_dat->mdio_bus_data), > > + GFP_KERNEL); > > This is not indented properly. > > On the second and subsequent lines of a multi-line function call, > the lines should start exactly at the first column after the openning > parenthesis of the first line. > > You must use the correct number of TAB and SPACE characters necessary > to do so.
