Subject: iio: exynos-adc: request second interupt only when touchscreen mode is used
From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>
commit 865b080e3229102f160889328ce2e8e97aa65ea0 upstream.
Second interrupt is needed only when touchscreen mode is used, so don't
request it unconditionally. This removes the following annoying warning
during boot:
exynos-adc 14d10000.adc: error -ENXIO: IRQ index 1 not found
