From de3f233703080bfbbd5861d27660db7a2e476238 Mon Sep 17 00:00:00 2001 From: Tuomas Tynkkynen Date: Thu, 25 Jul 2013 21:38:02 +0300 Subject: [PATCH] usb: host: tegra: Remove leftover code ehci-tegra calls devm_usb_get_phy, which will never succeed since the Tegra PHY does not register itself with the PHY subsystem. It is also completely redundant since the code has already located a PHY via an internal API. Call otg_set_host unconditionally to simplify the code since it should be safe to do so.
