Yes and no. =) Wrapping defines in do {} while(0) is nice when you are
using the defined constants inside functions. module_init() OTOH is
never used inside a function and your suggestion leads to compile
errors:
CC arch/i386/kernel/dmi_scan.o
CC arch/i386/kernel/bootflag.o
arch/i386/kernel/bootflag.c:99: error: parse error before "do"
