Subject: [PATCH] phy: qcom-qmp: fix struct clk leak on probe errors
commit f0a4bc38a12f5a0cc5ad68670d9480e91e6a94df upstream.
Make sure to release the pipe clock reference in case of a late probe
error (e.g. probe deferral).
Fixes: e78f3d15e115 ("phy: qcom-qmp: new qmp phy driver for qcom-chipsets")
