From 721002ec1dd55a52425455826af49cf8853b2d4f Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Fri, 22 Jun 2012 17:02:45 +0530 Subject: usb: otg: utils: rename function name in OTG utils _transceiver() in otg.c is replaced with _phy. usb_set_transceiver is replaced with usb_add_phy to make it similar to other usb standard function names like usb_add_hcd.
