If there are more than one external interrupts pending at the same time, acking the first interrupt by reading pending register then OR the corresponding bit and write back to pending register will also clear other interrupt pending bits. That will cause loss of interrupt. Signed-off-by: Da Yu Signed-off-by: Kumar Gala --- Reading git-diff-tree failed
