Xiubo Li d6b41cb060 regmap: fix possible ZERO_SIZE_PTR pointer dereferencing error. 
Since we cannot make sure the 'val_count' will always be none zero
here, and then if it equals to zero, the kmemdup() will return
ZERO_SIZE_PTR, which equals to ((void *)16).

So this patch fix this with just doing the zero check before calling
kmemdup().
