From 2ce2c3ac8852cfc8f74f4b7b9a2c4cdff007f96a Mon Sep 17 00:00:00 2001 From: Pavankumar Kondeti Date: Mon, 2 May 2011 11:56:33 +0530 Subject: [PATCH] USB: OTG: msm: Clear in_lpm flag before enabling the IRQ in resume The current code is clearing in_lpm flag after enabling the IRQ. If IRQ comes immediately before in_lpm flag is set, it thinks that hardware is in low power mode and disables the IRQ. Fix this by clearing in_lpm flag before enabling the IRQ.
