From 77f754c4335d87e785cb0b85cc81e4f16d610fe5 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Mon, 18 Aug 2008 17:42:04 -0700 Subject: [PATCH] usb gadget: link fixes for MIDI gadget Change how the MIDI gadget driver builds: don't use separate compilation, since it works poorly when key parts are library code (with init sections etc). Instead be as close as we can to "gcc --combine ...".
