Subject: mm/hwpoison: remove unneeded variable unmap_success
Patch series "Cleanups and fixup for hwpoison"
This series contains cleanups to remove unneeded variable, fix some
obsolete comments and so on. Also we fix potential pte_unmap_unlock on
wrong pte. More details can be found in the respective changelogs.
This patch (of 4):
unmap_success is used to indicate whether page is successfully unmapped
but it's irrelated with ZONE_DEVICE page and unmap_success is always true
here. Remove this unneeded one.
