From a6446829f841bf108fca8ca1e8f4f67b3a59d86c Mon Sep 17 00:00:00 2001 From: Kaushlendra Kumar Date: Mon, 3 Nov 2025 13:36:27 +0530 Subject: [PATCH] init: Replace simple_strtoul() with kstrtouint() in root_delay_setup() Replace deprecated simple_strtoul() with kstrtouint() for better error handling and input validation. Return 0 on parsing failure to indicate invalid parameter, maintaining existing behavior for valid inputs. The simple_strtoul() function is deprecated in favor of kstrtoint() family functions which provide better error handling and are recommended for new code and replacements.
