If anyone has any objections, please let me know. ------------------ From: Alexey Brodkin <Alexey.Brodkin@...opsys.com> commit dfc50fcaad574e5c8c85cbc83eca1426b2413fa4 upstream. Current check of phydev with IS_ERR(phydev) may make not much sense because of_phy_connect() returns NULL on failure instead of error value. Still for checking result of phy_connect() IS_ERR() makes perfect sense. So let's use combined check IS_ERR_OR_NULL() that covers both cases.
