[PATCH] m68k: irq_node.handler() should return irqreturn_t

From: Geert Uytterhoeven
Date: Thu Mar 26 2009 - 04:54:54 EST


commit b5dc7840b3ebe9c7967dd8ba73db957767009ff9 ("m68k: introduce irq
controller") reverted the return type of struct irq_node.handler() from
irqreturn_t to int. Change it back to irqreturn_t, else it will give a
compiler warning when irqreturn_t is turned into an enum in the near future:

| arch/m68k/kernel/ints.c:231: warning: assignment from incompatible pointer type

We already hit the warning in linux-next, which has commit
bedd30d986a05e32dc3eab874e4b9ed8a38058bb ("genirq: make irqreturn_t an enum")
