Colin Ian King 1d08f59081 phy: sun4i-usb: fix dereference of pointer phy0 before it is null checked ... [ Upstream commit 38b1927e5b ] Currently pointer phy0 is being dereferenced via the assignment of phy on the call to phy_get_drvdata before phy0 is null checked, this can lead to a null pointer dereference. Fix this by performing the null check on phy0 before the call to phy_get_drvdata. Also replace the phy0 == NULL check with the more usual !phy0 idiom.
