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

ptp: vmclock: Set driver data before its usage

If vmclock_ptp_register() fails during probing, vmclock_remove() is
called to clean up the ptp clock and misc device.
It uses dev_get_drvdata() to access the vmclock state.
However the driver data is not yet set at this point.

Assign the driver data earlier.
