Hi Steven,
Could you take a look at this patch, please?
2016-09-19 3:03 GMT+09:00 Masahiro Yamada <yamada.masah...@socionext.com>:
> In many of clk_disable() implementations, it is a no-op for a NULL
> pointer input, but this is one of the exceptions.
>
> Making it treewide consistent will allow clock consumers to call
> clk_disable() without NULL pointer check.
