Summary
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().
