      iwlwifi: warn if firmware image doesn't exist · befe9b6f
      Johannes Berg authored
      
      
      If the firmware image that we attempt to load doesn't
      actually exist we have a broken firmware file or other
      code not checking things correctly, so warn in such a
      case. Also avoid assigning cur_ucode/ucode_loaded then.

      iwlwifi: mvm: add missing break in debugfs · cbb346f2
      Johannes Berg authored
      
      
      When writing the disable_power_off value, the LPRX
      enable value also gets written unintentionally, so
      fix that by adding the missing break statement.

      iwlwifi: pcie: move warning message into warning · bcbb8c9c
      Johannes Berg authored
      
      
      Having a WARN_ON() followed by a printed message is
      less useful than having the message in the warning
      so move the message.

      iwlwifi: mvm: BT Coex fix NULL pointer dereference · 22cba0c0
      Emmanuel Grumbach authored
      
      
      When we disassociate, mac80211 removes the station and
      then, it sets the bss it unsets the assoc bool in bss_info.
      
      Since the firwmware wants it the opposite (first set the
      MAC context as unassoc, and only then, remove the STA of
      the API), we have a small period of time in which the STA
      in firmware doesn't have a valid ieee80211_sta pointer.
      During that time, iwl_mvm_vif->ap_sta_id, is still set
      to the STA in firmware that represent the AP.
      
      This avoids:
