Subject: pstore/ram_core: Do not reset restored zone's position and size
X-Git-Tag: firefly_0821_release~3680^2~2578^2~6
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=25b63da64708212985c06c7f8b089d356efdd9cf;p=firefly-linux-kernel-4.4.55.git

pstore/ram_core: Do not reset restored zone's position and size

Otherwise, the files will survive just one reboot, and on a subsequent
boot they will disappear.
