From d2d89271ea794cb8d7fd900eb7246053ec7a7b94 Mon Sep 17 00:00:00 2001 From: Old-Ding <35417409+Old-Ding@users.noreply.github.com> Date: Mon, 6 Jul 2026 06:14:04 +0800 Subject: drivers: fix fan53555 slew rate bounds check Valid slew_rates indices are 0 through RT_ARRAY_SIZE(slew_rates) - 1. The current check rejects only values greater than the table size, allowing slew_idx == RT_ARRAY_SIZE(slew_rates) to index one element past the table.
