This one is not needed, and can be removed. Why ? The output port of a uC (at least AVRs and PICs, but not 8051s) are push-pull.
You need to be careful here: There is a quite prominent exception to the push/pull outputs in PIC controllers: output RA4 (bit 5 of PORTA), for example, is an open drain output with many models, so you will always need a pullup there to create a logic 1.
With AVR controllers there isn't a problem because you can (software-)activate internal pullups.
