Subject: ip-addrlabel: Fix printing of label value
X-Git-Tag: v4.19.0~17
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b9b0d08c29f9aa6cc1b83c853964d9cc18dc6f2;p=thirdparty%2Fiproute2.git

ip-addrlabel: Fix printing of label value

Passing the return value of RTA_DATA() to rta_getattr_u32() is wrong
since that function will call RTA_DATA() by itself already.

Fixes: a7ad1c8a6845d ("ipaddrlabel: add json support")
