]I think you misinterpreted the Coding Standard.

]It is OPTIONAL whether or not the BOOLEAN variable is explicitly compared.

What you say is consistent with the existing EDK2 code, where many examples
of both forms can be found. On the other hand, table 10 on page 48 of the
coding document lists "If (Done == TRUE)"** under the heading Incorrect, and
lists "if (Done)" under the heading Correct.

** Sad part is that the entire column labeled 'Incorrect' is not even valid
C code due to the capitalization of 'if'.
Thanks,
Scott

]So, while the change is superfluous, I don't see anything wrong with it.
