From 743411b3f3e96e8ac4cae73551a0a95392fed1ea Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 1 Dec 2010 13:22:05 +0200 Subject: usb: musb: make all glue layer export struct musb_platform_ops preparing to a big refactor on musb code. We need to be able to compile in all glue layers (or at least all ARM-based ones) together and have a working binary. While preparing for that, we move every glue layer to export only one symbol, which is a struct musb_platform_ops, and make all other functions static. Later patches will come to allow for compiling all glue layers together and have a working binary.
