Subject: staging: fsl-dpaa2/ethsw: Fix uninitialized variables
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=13b72b089b9c9520a6ebeb388436a9ee14322279;p=linux.git

staging: fsl-dpaa2/ethsw: Fix uninitialized variables

Functions port_vlans_add() and port_vlans_del() could,
in theory, return an uninitialized variable. Fix this
by initializing the variable in question at declaration.
