The cap11xx devices have three hardware identification registers which are currently marked as volatile, preventing caching of those registers. This is not ideal since the registers should never change at runtime, we should be able to cache the value after the first read. Stop marking the registers as volatile, we don't have register defaults specified in the driver so this will result in reading from the hardware on first use.
