From 840008bb5162f029d5bc05959c7f51a3e8f9e0ff Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 25 Jan 2013 17:09:55 -0500 Subject: [PATCH] USB: UHCI: notify usbcore about port resumes This patch (as1651) adds calls to the new usb_hcd_{start,end}_port_resume() functions to uhci-hcd. Now UHCI root hubs won't be runtime suspended while they are sending a resume signal to one of their ports.
