From 865b080e3229102f160889328ce2e8e97aa65ea0 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski m.szyprowski@samsung.com Date: Mon, 9 Oct 2023 12:14:12 +0200 Subject: [PATCH] iio: exynos-adc: request second interupt only when touchscreen mode is used

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
