Subject: swconfig: Bugfix switch_port uci option parsing
X-Git-Tag: v18.06.0-rc1~3516
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=df9e7b1b269f4bd617cd8eb1b8f8a0d9ecb57160;p=oweals%2Fopenwrt.git

swconfig: Bugfix switch_port uci option parsing

When not defining 'device' or 'vlan' in relevant switch_port uci
sections, behaviour is inconsistent due to *devn, *port and *vlan
pointers not being zero initialized.
