[PATCH] USB: mark various usb tables const
patch below marks various USB tables and variables as const so that they end up in .rodata section and don't cacheline share with things that get written to. For the non-array variables it also allows gcc to optimize more. Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
