From e5b33fa47792375ca7fc49ccadee87d8e4b72929 Mon Sep 17 00:00:00 2001 From: Xueqin Luo Date: Mon, 31 Aug 2026 13:44:38 +0800 Subject: [PATCH] cpufreq: sparc-us2e: fix frequency table index copy-paste error In us2e_freq_cpu_init(), the last two frequency writes both use index [2] instead of [3] and [4] respectively, and the terminator uses [3] instead of [5]. This is a copy-paste error where the index was not incremented, causing the divider-6 and divider-8 entries to overwrite the already-written divider-4 entry. As a result, only three frequency steps (div 1, 2, and 4) are actually available to the cpufreq core, while the intended dividers 6 and 8 are silently lost. The struct us2e_freq_percpu_info::table[6] has room for 5 entries plus a terminator, matching the 5 hardware dividers. Fix the indices so all five frequency steps are correctly populated: table[0]=div1, table[1]=div2, table[2]=div4, table[3]=div6, table[4]=div8, table[5]=TABLE_END.
