[PATCH 4.9 05/32] net: mdio-mux: bcm-iproc: fix wrong getter and setter pair

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anton Vasilyev <vasilyev@xxxxxxxxx>

[ Upstream commit b0753408aadf32c7ece9e6b765017881e54af833 ]

mdio_mux_iproc_probe() uses platform_set_drvdata() to store md pointer
in device, whereas mdio_mux_iproc_remove() restores md pointer by
dev_get_platdata(&pdev->dev). This leads to wrong resources release.

The patch replaces getter to platform_get_drvdata.
