At the end of this structure, there is the 'channels' flex array. Each element is of type 'struct ieee80211_channel'. So only 1 element is allocated in this array.  When doing:   mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels; We point at the first element of the 'channels' flex array. So this is fine.  However, when doing:   mvm->nvm_data->bands[0].bitrates = \t\t\t(void *)((u8 *)mvm->nvm_data->channels + 1); because of the \"(u8 *)\" cast, we add only 1 to the address of the beginning of the flex array.  It is likely that we want point at the 'struct ieee80211_rate' allocated just after.
