From 9b9322db5c5a1917a66c71fe47c3848a9a31227e Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Wed, 14 Mar 2018 20:02:59 +0100 Subject: [PATCH] brcmfmac: Fix check for ISO3166 code The commit "regulatory: add NUL to request alpha2" increases the length of alpha2 to 3. This causes a regression on brcmfmac, because brcmf_cfg80211_reg_notifier() expect valid ISO3166 codes in the complete array. So fix this accordingly.
