can: peak_usb: constify struct peak_usb_adapter
A "struct peak_usb_adapter" describes a certain USB adapter, as this doesn't change during runtime, this patch marks all USB adapter definitions as const. Acked-by: Stephane Grosjean <s.grosjean@peak-system.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
