From d97cc2f2e938547a47daef29bc10ab38600a3310 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 22 Dec 2005 17:05:18 -0800 Subject: [PATCH] [PATCH] USB: ehci fix driver model wakeup flags On some systems, EHCI seems to be getting IRQs too early during driver setup ... before the root hub is allocated, in particular, making trouble for any code chasing down root hub pointers! In this case, it seems to be safe to just ignore the root hub setting. Thanks to Rafael J. Wysocki for getting this properly tested.
