From fb37fdd02856e45e78209d32522029c9f77fe7b7 Mon Sep 17 00:00:00 2001 From: Cheng Ziqiu Date: Tue, 14 Mar 2023 15:01:30 +0800 Subject: [PATCH] iio: adc: at91-sama5d2_adc: remove dead code in at91_adc_probe() From the comment of platform_get_irq(), it only returns non-zero IRQ number and negative error number, other than zero. Fix this by removing the if condition.
