Alexan E / Mbed 2 deprecated GPIO_interrupts

A simple example that uses the GPIO group and pin interrupts. LED1 turns on when P21 and P22 are grounded (using group 0 interrupt) LED1 turns of when P23 or P24 are grounded (using group 1 interrupt) LED2 turns on when P19 is grounded (using GPIO interrupt 0) LED2 turns off when P18 is grounded (using GPIO interrupt 1)

Revision:
2:7c8d0f7dd79f
Parent:
1:566ac56c130e 
Changed interrupt priority comment, the CortexM0 has four levels 0-3.

Moved the SetPriority function before the interrupt enable. In CortexM0 the priority shouldnt be changed while the interrupt is enabled

Who changed what in which revision?
