Pull trivial pstore update from Tony Luck:
 "Couple of pstore cleanups"

It turns out that the kmemdup() conversion ends up being undone by the
fact that the memory block also needed the ecc information (see commit
bd08ec33b5c2: "pstore/ram: Restore ecc information block"), so all that
remains after merging is the error return code change.
