Subject: [PATCH v2] usb: musb: Fix external abort in musb_remove on omap2430
Date: Thu, 8 Mar 2018 23:19:48 +0100 [thread overview]
Message-ID: <20180308221949.12054-1-merlijn@wizzup.org> (raw)
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.
