Perhaps we could make it:
phy->label = kstrdup(label, GFP_KERNEL);
and free the label in phy_destroy() ?
That way the users would't need to keep the label around. It might
be useful when PHY provider generates the labels dynamically. I guess
it is OK for PHY providers to hard code the labels and having the PHY
user drivers passed labels in platform data ?

Isn't kfree(phy); missing here ?
