Disable " Macro argument reuse 'a' - possible side-effects?"

[tsafin]

checkpatch.pl produces totally bogus warning about side-effect of macro arguments use:

I looked around and some suggest to introduce absolutely useless tricks to shut this warning out, like

i.e. we introduce local variable inside of macro body typed as typeof of argument, just to make it to allow to use this argument multiple times. This make no much sense and this warning is simply bug. Please disable it
