4.17-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.
