Please provide a bit more description as to why this fixes the issue.

The pending register is write 1 clear.  If there are more than one
external interrupts pending at the same time, acking the first
interrupt will also clear other interrupt pending bits.  That will
cause loss of interrupt.

Thanks.  That should be included in the commit message.
