From ebb3ca3b4477bbc118976c77fe1913507df718ec Mon Sep 17 00:00:00 2001 From: Luca Coelho Date: Wed, 29 May 2019 15:25:29 +0300 Subject: [PATCH] cfg80211: use BIT_ULL in cfg80211_parse_mbssid_data() The seen_indices variable is u64 and in other parts of the code we assume mbssid_index_ie[2] can be up to 45, so we should use the 64-bit versions of BIT, namely, BIT_ULL().
