Subject[PATCH 4.19 041/131] USB: ohci-sm501: Add missed iounmap() in remove
Date
From: Chuhong Yuan <hslester96@gmail.com>

commit 07c112fb09c86c0231f6ff0061a000ffe91c8eb9 upstream.

This driver misses calling iounmap() in remove to undo the ioremap()
called in probe.
Add the missed call to fix it.
