Subject: fs/nfs: remove unnecessary new_valid_dev check
X-Git-Tag: firefly_0821_release~176^2~745^2~3
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=118c9163562426face9ff0903f1cbd3e1a959ca9;p=firefly-linux-kernel-4.4.55.git

fs/nfs: remove unnecessary new_valid_dev check

As new_valid_dev always returns 1, so !new_valid_dev check is not
needed, remove it.
