## Overview

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

phy: qcom: qmp-usb-legacy: Fix possible NULL-deref on early runtime suspend

There is a small window where the runtime suspend callback may run
after pm_runtime_enable() and before pm_runtime_forbid(). In this
case, a crash occurs because runtime suspend/resume dereferences
qmp->phy pointer, which is not yet initialized:
        `if (!qmp->phy->init_count) {`

This can also happen if user re-enables runtime-pm via the sysfs
attribute before qmp phy is initialized.

Similarly to other qcom phy drivers, introduce a qmp->phy_initialized
variable that can be used to avoid relying on the possibly uninitialized
phy pointer.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
