Subject: [PATCH v2 1/2] net: phy: mscc: move shared probe code into a helper
Date: Tue,  9 Jun 2020 15:31:39 +0200	[thread overview]
Message-ID: <20200609133140.1421109-1-heiko@sntech.de> (raw)

From: Heiko Stuebner <heiko.stuebner@theobroma-systems.com>

The different probe functions share a lot of code, so move the
common parts into a helper to reduce duplication.
