The final check of hubp for NULL covers all remaining lines of code, since
the value of hubp does not change until the end of the method.
This check is redundant because hubp1 is already dereferenced within the
macro.
If it were NULL, the program would have already failed to proceed.
Remove the left part of the expression with the logical "&&".
