[OpenWrt-Devel] [PATCH 4/4] blobmsg_add_json_from_file(): fixed const-correctness with libjson

I've checked the source of json_object_from_file(char*) and the buffer walks directly into open(3) and vsyslog(3). open(3) takes a const buffer while vsyslog(3) takes a varargs list which doesn't tinker with the buffer, too.

You are completely right, Felix, and a cast is enough.
