Description

In the Linux kernel, the following vulnerability has been resolved: phy: qcom-qmp: fix reset-controller leak on probe errors Make sure to release the lane reset controller in case of a late probe error (e.g. probe deferral). Note that due to the reset controller being defined in devicetree in "lane" child nodes, devm_reset_control_get_exclusive() cannot be used directly.
