Using register asm statements has been proven to be very error prone, especially when using code instrumentation where gcc may add function calls, which clobbers register contents in an unexpected way. Therefore get rid of register asm statement in dasd code, even though there is currently nothing wrong with it. This way we know for sure that the above mentioned bug class won't be introduced here.
