Subject: vfs: show_vfsmnt: remove redundant initialization of error code
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5d9f3c7b620f6d1d9555223817bdfddfbd4b93a0;p=deliverable%2Flinux.git

vfs: show_vfsmnt: remove redundant initialization of error code

As err variable is now always checked right after the first assignment,
its initialization is redundant and could be safely removed.
