PPC32/64 defines NO_IRQ to zero, so no problems expected. ARM defines NO_IRQ to -1, but OF code relies on IRQ domains support, which returns correct ('0') value in 'no irq' case. So everything should be fine. Other arches might break if some of their OF drivers rely on NO_IRQ being not 0. If so, the drivers must be fixed, finally. [ Rob Herring points out that microblaze should be fixed, and has posted a patch for testing for that. - Linus ] Signed-off-by: NAnton Vorontsov <anton.vorontsov@linaro.org> Acked-by: NWolfram Sang <w.sang@pengutronix.de> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
