From c09ddcdd4dd32ee9768dc233ead4b3d726f26d38 Mon Sep 17 00:00:00 2001 From: Ruan Jinjie Date: Thu, 27 Jul 2023 21:16:07 +0800 Subject: [PATCH] iio: adc: fix the return value handle for platform_get_irq() There is no possible for platform_get_irq() to return 0 and the return value of platform_get_irq() is more sensible to show the error reason.
