Analyze and fix the following issue in the Linux kernel code: ieee1394: fix broken signed char assumption.
Problem Details: "ack_code" is assigned (and tested against) negative numbers, but was declared as "char". Which only works if "char" is signed - which it necessarily isn't. So make that signedness assumption specific.
