From 2c1fe89db1cfa9826c94e848c14dc68de0e2b0d5 Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Sun, 24 Mar 2013 17:36:54 +0200 Subject: usb: musb: omap2430: turn off vbus on cable disconnect On USB_EVENT_ID event the musb glue enables VBUS by calling omap2430_musb_set_vbus(musb, 1) that sets the session bit, but on USB_EVENT_NONE reverse action is never made, and that breaks PM. Disable VBUS on USB_EVENT_NONE to be sure musb session is ended on cable unplug so that PM works.
