[PATCH 4.9 10/74] usb: musb: Fix external abort in musb_remove on omap2430

[Greg Kroah-Hartman]

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

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

From: Merlijn Wajer <merl...@wizzup.org>

commit 94e46a4f2d5eb14059e42f313c098d4854847376 upstream.

This fixes an oops on unbind / module unload (on the musb omap2430
platform).

musb_remove function now calls musb_platform_exit before disabling
runtime pm.
