Descriptions

In the Linux kernel, the following vulnerability has been resolved: phy: qcom: qmp-usb: fix NULL-deref on runtime suspend Commit 413db06c05e7 ("phy: qcom-qmp-usb: clean up probe initialisation")
removed most users of the platform device driver data, but mistakenly
also removed the initialisation despite the data still being used in the
runtime PM callbacks. Restore the driver data initialisation at probe to avoid a NULL-pointer
dereference on runtime suspend. Apparently no one uses runtime PM, which currently needs to be enabled
manually through sysfs, with this driver.
