From d1e3d757f7aa91f15db347fc05ffd7ef7f413091 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 24 Jan 2013 22:29:48 +0200 Subject: usb: common: introduce usb_state_string() this function will receive enum usb_device_state and return a human-readable string from it or, case an unknown value is passed as argument, the string "UNKNOWN".

While doing that, we also delete otg.c since it's now empty.
