Subject: [PATCH v2 1/2] PCI: qcom: Fix runtime PM imbalance on probe errors
Date:   Fri,  1 Apr 2022 15:38:53 +0200
Message-Id: <20220401133854.10421-2-johan+linaro@kernel.org>
In-Reply-To: <20220401133854.10421-1-johan+linaro@kernel.org>

Precedence: bulk

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.

Fixes: 6e5da6f7d824 ("PCI: qcom: Fix error handling in runtime PM support")
