Subject: blobmsg: add blobmsg_parse_attr function
X-Git-Url: http://git.openwrt.org/feed/routing.git;lede-17.01?a=commitdiff_plain;h=b09b316aeaf6282bf2d2f7df9d2cc2cdf3977691;p=project%2Flibubox.git

blobmsg: add blobmsg_parse_attr function

This allows turning the common pattern of:
  blobmsg_parse(policy, ARRAY_SIZE(policy), tb, blobmsg_data(data), blobmsg_len(data));

into:
  blobmsg_parse_attr(policy, ARRAY_SIZE(policy), tb, data);
