Subject: base-files: config_get: prevent filename globbing
X-Git-Tag: v18.06.2~1
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=cddd7b4c778a68194319630274b1849e8f788a89;p=oweals%2Fopenwrt.git

base-files: config_get: prevent filename globbing

When config_get is called as "config_get section option" the option
is unexpectedly globbed by the shell which differs from the way options
are read to a variable with "config_get variable section option".
Add another layer of double quotes to fix it.
