From 8aa6f7697f5981d336cac7af6ddd182a03c6da01 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Thu, 22 Jan 2026 18:20:12 +0100 Subject: [PATCH] pmdomain: qcom: rpmpd: fix off-by-one error in clamping to the highest state As it is indicated by the comment, the rpmpd_aggregate_corner() function tries to clamp the state to the highest corner/level supported by the given power domain, however the calculation of the highest state contains an off-by-one error. The 'max_state' member of the 'rpmpd' structure indicates the highest corner/level, and as such it does not needs to be decremented. Change the code to use the 'max_state' value directly to avoid the error.
