[PATCH 4/8] USB: Ethernet: allow optional removal of __init and__init_data tags
From: Michal Nazarewicz
Date: Wed Apr 07 2010 - 09:43:22 EST
Use the __usb_init and __usb_initdata tags in Ethernet
composite function related files to allow disabling the init
section micro-optimisation in drivers that require this.
