mfd: ucb1x00: Allow IRQ probing to work with IRQs > 32
probe_irq_on() only returns non-zero if it found any interrupts below IRQ32 which could be probe candidates. If all the probable interrupts are higher than 32, then this will cause a failure. Fix this. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Lee Jones <lee.jones@linaro.org>
