From 39dbd7df5632ac083caa01641cea831b1fe3a3ac Mon Sep 17 00:00:00 2001 From: Manjunath Goudar Date: Fri, 4 Oct 2013 09:58:14 +0530 Subject: [PATCH] USB: OHCI: Properly handle ohci-platform suspend Suspend scenario in case of ohci-platform glue was not properly handled as it was not suspending generic part of ohci controller.Alan Stern suggested, properly handle ohci-platform suspend scenario. Calling explicitly the ohci_suspend() routine in ohci_platform_suspend() will ensure proper handling of suspend scenario.
