From 09fc7d22b024692b2fe8a943b246de1af307132b Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 24 Apr 2013 17:21:42 +0300 Subject: usb: musb: fix incorrect usage of resource pointer We can't simply pass the resource pointer from our device down to our children, otherwise module reinsertion will not work as the resource will continue to be marked as busy. Fix it by building a proper struct resource for our child musb device.
