From ba7ee8bb313c4a55066c4da30292aeb9abac82d8 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 26 Feb 2015 11:31:49 -0600 Subject: [PATCH] usb: musb: don't touch devctl from babble recovery We do *not* want to touch devctl at all when trying to recover from babble. All we want to do is mask IRQs until we're done without our babble recovery, at which point we will unmask IRQs.
