I don't see why you made your changes in this awkward way. For
instance...

Why rename this variable? Wasn't the original name good enough?

Why make two changes, resulting in more code, when you could have made
just one change?
phy = devm_of_phy_get(dev, child, NULL);
+ exynos_ehci->phy[phy_num] = phy;
Also, the patch description should mention that you are adding support
for EPROBE_DEFER.
