[PATCH v7 1/4] usb: musb: core: Handle Babble condition only in HOST mode

From: George Cherian
Date: Wed Jul 16 2014 - 08:54:22 EST


BABBLE and RESET share the same interrupt. The interrupt
is considered to be RESET if MUSB is in peripheral mode and
as a BABBLE if MUSB is in HOST mode.

Handle babble condition iff MUSB is in HOST mode.
