Subject: [PATCH 5.10 369/452] PCI: qcom: Fix runtime PM imbalance on probe errors
From: Johan Hovold <johan+linaro@...nel.org>
commit 87d83b96c8d6c6c2d2096bd0bdba73bcf42b8ef0 upstream.
Drop the leftover pm_runtime_disable() calls from the late probe error
paths that would, for example, prevent runtime PM from being reenabled
after a probe deferral.
Link: https://lore.kernel.org/r/20220401133854.10421-2-johan+linaro@kernel.org
Fixes: 6e5da6f7d824 ("PCI: qcom: Fix error handling in runtime PM support")
