Subject: [PATCH v2 05/10] phy: un-inline devm_mdiobus_register()

From: Bartosz Golaszewski <[email-masked]>
Date: Mon, 29 Jun 2020 14:03:41 +0200

From: Bartosz Golaszewski <[email-masked]>

Functions should only be static inline if they're very short. This
devres helper is already over 10 lines and it will grow soon as we'll
be improving upon its approach. Pull it into mdio_devres.c.
