From b0ad5e8b4905d2398702e1dde033bce9c2c0fcad Mon Sep 17 00:00:00 2001 From: Patrik Flykt Date: Fri, 21 Nov 2014 15:08:02 +0200 Subject: [PATCH] mac80211_hwsim: Send alpha2 only if non-zero A properly set alpha2 value consists of two chars that both contain letters or digits. If no value is set, both chars keep their initial value zero. Therefore do not send the alpha2 parameter to user space if either of the characters has been left at its initial zero value.
