As of commit 306c342f9cb1 ("clk: Replace of_clk_get_by_clkspec() with
of_clk_get_from_provider()") in -next, you must use of_clk_get_from_provider()
instead.

As of commit 4716bafa1f63 ("lib/vsprintf: Add %pC{,n,r} format specifiers
for clocks") in -next, you can use "%pC" to print the clock's name.
