[PATCH 1/2] pmdomain: core: Update the rejected/usage counters at system suspend too

From: Ulf Hansson
Date: Fri Apr 12 2024 - 06:42:33 EST


During system suspend we may try to enter a low power-state for the genpd
in question. Let's take this into account for the statistics too, by
updating the rejected/usage counters for the corresponding state.
