From 0021a75a475b6c1e500ae4bdcc1ff19f7794aa95 Mon Sep 17 00:00:00 2001 From: Vivek Gautam Date: Tue, 8 Apr 2014 20:10:35 +0530 Subject: [PATCH] usb: ohci-exynos: Remove locks for 'ohci' in suspend callback Patch : 14982e3 USB: OHCI: Properly handle ohci-exynos suspend has already removed 'ohci_hcd' settings from exynos glue layer as a part of streamlining the ohci controller's suspend. So we don't need the locks for 'ohci_hcd' anymore.
