Also, your subject and changelog body here are identical, please be much more verbose in the body explaining why you are doing something, not just what you are doing. And your subject line should also match other patches for this file, and have "usb: phy: ..." in the beginning. > --- > drivers/usb/phy/phy.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/usb/phy/phy.c b/drivers/usb/phy/phy.c > index b47285f..de21967 > --- a/drivers/usb/phy/phy.c > +++ b/drivers/usb/phy/phy.c > @@ -59,7 +59,7 @@ static struct usb_phy *__usb_find_phy(struct list_head *list, > > static struct usb_phy *__of_usb_find_phy(struct device_node *node) > { > - struct usb_phy *phy; > + struct usb_phy *phy = NULL; Why isn't the compiler complaining about this today?
