Remove unnecessary equality check

Browse Source 
Currently `if` statement includes an assignment (from a function return
value) and a equality check. The parenthesis are in the incorrect place,
currently the code clobbers the function return value because of this.

We can fix this by simplifying the `if` statement.

`if (foo != 0)`

can be more succinctly expressed as

`if (foo)`

Remove the equality check, add parenthesis to correct the statement.
