Subject: [PATCH v2 1/3] phy: qcom-qmp: fix struct clk leak on probe errors
Date: Wed, 27 Apr 2022 08:32:41 +0200	[thread overview]
Message-ID: <20220427063243.32576-2-johan+linaro@kernel.org> (raw)
In-Reply-To: <20220427063243.32576-1-johan+linaro@kernel.org>

Make sure to release the pipe clock reference in case of a late probe
error (e.g. probe deferral).
