When allocating an array of elements, users should check for
multiplication overflow or preferably use one of the provided helpers
like: devm_kmalloc_array().

This provides devm_krealloc_array() for users who want to reallocate
managed arrays.

As this is going into a very generic place I'd like a relevant ack.
That file is a bit of a wild west for acks, but Greg seems most
appropriate person.

So Greg, any comments on this one?

As there is only 1 user of this function in the patch series, you don't
save any extra code space here, I don't think this is worth it.

We are seeing less and less gains from these new devm_* additions, and
only more confusion and problems with them.  So perhaps don't add this?
I don't think it is needed.

thanks,

greg k-h
