[PATCH v4 1/3] net: phy: mscc: move shared probe code into a helper
From: Heiko Stuebner
Date: Wed Jun 17 2020 - 17:33:57 EST
From: Heiko Stuebner <heiko.stuebner@xxxxxxxxxxxxxxxxxxxxx>
The different probe functions share a lot of code, so move the
common parts into a helper to reduce duplication.
This moves the devm_phy_package_join below the general allocation
but as all components just allocate things, this should be ok.
