From ecf85e481a716cfe07406439fdc7ba9526bbfaeb Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Tue, 21 Apr 2009 20:33:10 -0700 Subject: USB: otg: Fix bug on remove path without transceiver In the case where a gadget driver is removed while no transceiver was found at probe time, a bug in otg_put_transceiver() will trigger. Provide symetric calls for otg_get_transceiver() and otg_put_transceiver(), wherever a transceiver was found or not.
