Hi Gregory,

I'm a bit confused by this. This patch fixes "clk: mvebu: add missing
CESA gate clk", right? That patch lives in clk-next. It was not pushed
to Linus' tree yet via a -fixes branch.

Thus I can just apply this patch to clk-next and the problem should be
resolved in clk-next, no?

Furthermore, I do not have 29e623475c50267ee3aaa49ebb6cbe107bce8d2a
anywhere in my tree. I'm not sure where this sha1 hash came from.

Regards,
Mike
