From: Alan Stern Date: Fri, 25 Jan 2013 22:09:55 +0000 (-0500) Subject: USB: UHCI: notify usbcore about port resumes X-Git-Tag: upstream/snapshot3+hdmi~5781^2~11 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=840008bb5162f029d5bc05959c7f51a3e8f9e0ff;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git 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.
