As there are other bugs to fix, I may put back the 'of_device_is_available',
but there are not 3 different changes: I just explain the visible
effects of the patch. The patch itself is, as the subject says,
'simplify code', that is, 'have a simpler code with no change in the

dai_link->cpu_of_node is 'const struct device_node *' and both
of_clk_get() and of_node_put() want 'struct device_node *'. So, there
must be a cast somewhere.
Do you prefer I put these ones when calling the 'of_xx' functions?
