Subject: knfsd: nfsd: remove superfluous assignment from nfsd_lookup
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=87548c37c8bdbf98aea002c9c04e4dc8aa27fe1b;p=openwrt%2Fstaging%2Fblogic.git

knfsd: nfsd: remove superfluous assignment from nfsd_lookup

The "err" variable will only be used in the final return, which always happens
after either the preceding

	err = fh_compose(...);

or after the following

	err = nfserrno(host_err);

So the earlier assignment to err is ignored.
