ieee1394: safer definition of empty macros
A deactivated macro, defined as "#define foo(bar)", will result in silent corruption if somebody forgets a semicolon after a call to foo. Replace it by "#define foo(bar) do {} while (0)" which will reveal any respective syntax errors. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
