From bcf40815e0cda371cecc242398fe39b873bb1047 Mon Sep 17 00:00:00 2001 From: Matthieu CASTET Date: Tue, 15 Feb 2011 18:40:28 +0100 Subject: [PATCH] USB: don't run ehci_reset in ehci_run for tdi device TDI driver does the ehci_reset in their reset callback. Don't reset in ehci_run because configuration settings done in platform driver will be reset. This will allow to make msm use ehci_run.
