Subject: [PATCH net v2 1/2] mdio-bitbang: Export mdiobb_{read,write}()
Date: Mon, 18 Jan 2021 16:06:55 +0100 [thread overview]
Message-ID: <20210118150656.796584-2-geert+renesas@glider.be> (raw)
In-Reply-To: <20210118150656.796584-1-geert+renesas@glider.be>
Export mdiobb_read() and mdiobb_write(), so Ethernet controller drivers
can call them from their MDIO read/write wrappers.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
