From 5d881802c407d83c169c875dad88fe2bba066c33 Mon Sep 17 00:00:00 2001 From: George Cherian Date: Mon, 26 May 2014 14:50:08 +0530 Subject: [PATCH] usb: musb: core: Handle Babble condition only in HOST mode 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.
