Subject: tweak "cast to same type" to not do bad things
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ab6475039d7535a6abda27c0124fdbe6502c211f;p=thirdparty%2Ffreeradius-server.git

tweak "cast to same type" to not do bad things

if no enumv is passed in, it shouldn't forcibly nuke the input
enumv.  This patch makes it easier to deal with FR_TYPE_ATTR
