From 41fff779d7948147f2440c4bb134cdf8b45b22d7 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Wed, 13 Jul 2022 14:28:18 -0700 Subject: [PATCH] clk: qcom: gdsc: Bump parent usage count when GDSC is found enabled When a GDSC is found to be enabled at boot the pm_runtime state will be unbalanced as the GDSC is later turned off. Fix this by increasing the usage counter on the power-domain, in line with how we handled the regulator state.
