Oh good grief, please stop wasting my time.  You have the definition
here in your patch:

> +	u32			rsvd1[2];

And then you use it as:

> +				pm8001_mr32(address, 0x38);

That last one goes over the array bounds because an array declared as
rsvdl1[2] only has two elements: 0 and 1 ... this isn't rocket science
or esoteric compiler flags, this is basic C.

Stop quibbling and fix it, please.
