The conversion to SPDX really feels like it should at least be called
out in the changelog, and probably a separate change.
will upload SPDX changes as a separate patch.

The driver should really check the return value of clk_set_rate(), it
can fail.
We will add checks for return value of clk_set_rate() and will upload
new version
