Description
===========

In the Linux kernel, the following vulnerability has been resolved:

usb: dwc3: qcom: Fix memory leak in dwc3_qcom_interconnect_init

of_icc_get() alloc resources for path handle, we should release it when not
need anymore. Like the release in dwc3_qcom_interconnect_exit() function.
Add icc_put() in error handling to fix this.

The Linux kernel CVE team has assigned CVE-2022-50633 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
