From mboxrd@z Thu Jan 1 00:00:00 1970 From: manjunath.goudar@linaro.org (Manjunath Goudar) Date: Wed, 12 Jun 2013 20:58:32 +0530 Subject: [PATCH 04/10] USB: OHCI: Properly handle ohci-ep93xx suspend In-Reply-To: <1371050918-29472-1-git-send-email-manjunath.goudar@linaro.org> References: <1371050918-29472-1-git-send-email-manjunath.goudar@linaro.org> Message-ID: <1371050918-29472-5-git-send-email-manjunath.goudar@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Suspend scenario in case of ohci-ep93xx glue was not properly handled as it was not suspending generic part of ohci controller.Calling explicitly the ohci_suspend() routine in ohci_hcd_ep93xx_drv_suspend() will ensure proper handling of suspend scenario.
