Hi Jaehee,
If you just want to remove the braces, your patch is good.
But... Did you ask yourself why this code needs to test if "pmlmepriv" is
valid before calling vfree() on it? Actually, the code doesn't need this
test, it just needs to call "vfree(pmlmepriv)" unconditionally.
OK, I know that this is not directly related to your patch or any other
that is explicitly made just for removing unnecessary braces...
vfree() behaves as a no-op function on NULL pointers, therefore there is no
need to test whether or not "pmlmepriv" is valid.
Thanks,
Fabio M. De Francesco
