Subject: nl80211: Fix PASN auth alg check on big-endian CPUs
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e592a1a7d63ba2cd1fcada63ca52a96b99ca3c9;p=thirdparty%2Fhostap.git

nl80211: Fix PASN auth alg check on big-endian CPUs

auth_type is set to a value that is already converted to host byte order
and as such the following comparison must not convert the defined value
to little-endian byte order.
