AFAIK Android updates are not as fast as they could be due to need for mobile operators to re-certify every update as the OS blob contains modem firmware. Apple is able to update iOS faster because modem firmware is separate from the rest of iOS. Hence having open source drivers in the kernel will not improve the situation much.
