FIT header verification in mkimage was treating a return code as a boolean, which meant that failures in validating the fit were seen as successes. Additionally, mkimage was checking all formats to find a header which passes validation, rather than using the image type specified to mkimage. checkpatch.pl checks for lines ending with '(' and alignment matching open parentheses are ignored to keep with existing coding style.
