Subject: [PATCH net 4/4] net/fsl: xgmac_mdio: Fix incorrect iounmap when removing module
Date: Sun, 16 Jan 2022 22:15:29 +0100	[thread overview]
Message-ID: <20220116211529.25604-5-tobias@waldekranz.com> (raw)
In-Reply-To: <20220116211529.25604-1-tobias@waldekranz.com>

As reported by sparse: In the remove path, the driver would attempt to
unmap its own priv pointer - instead of the io memory that it mapped
in probe.

Fixes: 9f35a7342cff ("net/fsl: introduce Freescale 10G MDIO driver")
