Subject: RADIUS DAS: Avoid compiler warning on abs()
X-Git-Tag: hostap_2_5~470
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=028b19675dcf696e8057aaec66c39f3f4066a48b;p=thirdparty%2Fhostap.git

RADIUS DAS: Avoid compiler warning on abs()

The input parameter ended up being converted to long int instead of int,
so use an explicit typecase to get rid of the compiler warning.
