I wasn't referring to a discussion with regards to this patch series. I'm
referring to what I believe was a discussion with Russell King on whether
a NULL from clk_get() should be considered a clock and whether it should
be usable as a "clock" with the clock APIs. That's the reason clk_get()
returns -ENOENT instead of NULL.
