My patch is in linux-next, but didn't make it into mainline so far.

Stephen, could you send this as a bugfix for the next -rc?

I'm not sure which patch you're talking about. I thought we already merged commit 7001ec560a82 (clk: vt8500: don't return possibly uninitialized data, 2016-02-01). It's in v4.6-rc1.

From what I recall the warning went away with your patch on your

compiler but doesn't go away on older versions of GCC. If there's another patch I'm not aware.
