of_clk_get_parent_count() and of_clk_get_parent_name() never modify the device nodes passed, so they can be const. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lkml.kernel.org/r/20200212094317.1150-1-geert+renesas@glider.be Signed-off-by: Stephen Boyd <sboyd@kernel.org>
