* ppc403/ictrl/ictrl.c (ictrl_isr): We acknolwegde the interrupt in
interrupt controller (clr_exisr(mask)) before calling the interrupt
handler that will acnowledge the interrupt source. This results in
the interrupt beeing seen a second time by the interrupt controller.
Reported and fixed by El Kolli Yacine <yacine.elkolli@crf.canon.fr>.
