Description OSIDB Bzimport 2025-02-26 03:11:01 UTC 
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.
