The 2 functions called from clk_disable_unprepare() already check that
the clock pointer is valid: no need to test it before calling it.

Now I get it. 'called from' != 'calling' (what I understood). But also
!= 'called by' (what I would have ecpected, but I am neither a native
speaker).
You mean "clk_disable_unprepare() is NULL pointer safe."

On Armada 7K/8K we need to explicitly enable the bus clock. The bus clock
is optional because not all the SoCs need them but at least for Armada
7K/8K it is actually mandatory.
The binding documentation is updating accordingly.
