[PATCH 2/4] USB: OTG: Make otg_get_transceiver() and otg_set_transceiver() generic

From: Felipe Balbi
Date: Sat Jan 19 2008 - 09:36:20 EST


From: Tony Lidgren <tony@xxxxxxxxxxx>

Move otg_get_transceiver() and otg_set_transceiver() from omap specific code
to common otg.c so other upcoming drivers can share them.
