best_rate is reported as potentially uninitialized by gcc. Signed-off-by: Boris Brezillon <redacted> Fixes: 155e8b3b0ee3 ("clk: bcm: Support rate change propagation on bcm2835 clocks") Reported-by: Stephen Rothwell <redacted>I wonder why I didn't get that. Which compiler version did you use?In case you're interested, my gcc [1] failed to detect it as well, and this is not the first time it happens :-/.

No, I see it now with gcc-7, it only just turned up in linux-next. I ran into it right away with an allmodconfig build. You were probably testing based on an earlier v4.9-rc release that had the warning globally disabled. Arnd
