NO_IRQ is used to check the return of irq_of_parse_and_map(). On some architecture NO_IRQ is 0, on other architectures it is -1. irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ. So use 0 instead of using NO_IRQ. Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> --- drivers/video/fbdev/mb862xx/mb862xxfbdrv.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
