From d2852f2d3e6d6b9de3739f95b5cd9eab3157af37 Mon Sep 17 00:00:00 2001 From: Bin Liu Date: Mon, 21 May 2018 08:42:18 -0500 Subject: [PATCH] usb: musb: remove references to default_a of struct usb_otg musb drivers do not use the otg fsm framework, so referencing to otg->default_a doesn't have any effect, so remove the references. But tusb6010 glue driver uses it locally to control the vbus power, so keep the references in tusb6010 only.
