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

serial: ma35d1: Fix clock reference leak in ma35d1serial_probe()

of_clk_get() returns a clock with a reference that has to be released
with clk_put(). ma35d1serial_probe() never does that, so the reference
is leaked on the probe error paths and also when the port is removed.

Release it on the error paths and in ma35d1serial_remove().
