Subject: blobmsg: reuse blobmsg_namelen in blobmsg_data
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=86f6a5b8d1f160cc6f278f08f69d2c3d0f90b43c;p=project%2Flibubox.git

blobmsg: reuse blobmsg_namelen in blobmsg_data

Move blobmsg_namelen into header file so it's possible to reuse it in
blobmsg_data.
