From 3379c900320954d768ed9903691fb2520926bbe3 Mon Sep 17 00:00:00 2001 From: Qianfeng Rong rongqianfeng@vivo.com Date: Mon, 1 Sep 2025 21:57:26 +0800 Subject: iio: dac: ad5421: use int type to store negative error codes

Change the 'ret' variable in ad5421_update_ctrl() from unsigned int to int, as it needs to store either negative error codes or zero returned by ad5421_write_unlocked().
