From e42f110700ed7293700c26145e1ed07ea05ac3f6 Mon Sep 17 00:00:00 2001 From: Johan Hovold johan+linaro@kernel.org Date: Tue, 2 May 2023 12:38:10 +0200 Subject: [PATCH] phy: qcom-qmp-pcie-msm8996: fix init-count imbalance
The init counter is not decremented on initialisation errors, which prevents retrying initialisation.
Add the missing decrement on initialisation errors so that the counter reflects the state of the device.
