From e5615112807c27dd256f0bd8fc8b1f6f5e1b90af Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Sun, 10 Mar 2013 02:48:55 +0200 Subject: [PATCH] usb: musb: core: honour initial transceiver state As the usb transceiver driver usually starts first, it should already have default_a variable set according to ID pin state, so don't override it. In case default_a was not changed by trasceiver, it will default to 0 and this code will work as before.
