Ok, I made you do this. Sorry. I assumed it you'd just audit initializers. I suggest to take this, anyway, but: > +++ b/drivers/extcon/extcon-axp288.c > @@ -446,6 +446,7 @@ static struct platform_driver axp288_extcon_driver = { > }; > > static struct device_connection axp288_extcon_role_sw_conn = { > + .fwnode = NULL, > .endpoint[0] = "axp288_extcon", > .endpoint[1] = "intel_xhci_usb_sw-role-switch", > .id = "usb-role-switch", This one is not neccessary as struct initializers are "filled" with 0s when no other value is present. > diff --git a/drivers/platform/x86/intel_cht_int33fe.c b/drivers/platform/x86/intel_cht_int33fe.c > index f40b1c19..1fa77e4 100644 > --- a/drivers/platform/x86/intel_cht_int33fe.c > +++ b/drivers/platform/x86/intel_cht_int33fe.c > @@ -175,15 +175,19 @@ static int cht_int33fe_probe(struct platform_device *pdev) > return -EPROBE_DEFER; /* Wait for i2c-adapter to load */ > } > > + data->connections[0].fwnode = NULL; And these should be already zero-initialized by data = devm_kzalloc(dev, sizeof(*data), GFP_KERNEL); Anyway, extra initializations will not hurt.
