The __iwl_mvm_resume() function always returns 1, which causes mac80211 to do a reconfig with IEEE80211_RECONFIG_TYPE_RESTART. This type of reconfig calls iwl_mvm_restart_complete(), where we unref the IWL_MVM_REF_UCODE_DOWN, so we should always take the reference in this case. This prevents this kind of warning from happening: [40026.103025] WARNING: at /root/iwlwifi/iwlwifi-stack-dev/drivers/net/wireless/iwlwifi/mvm/mac80211.c:236 iwl_mvm_unref+0xc9/0xd0 [iwlmvm]() [40026.105145] Modules linked in: iwlmvm(O) iwlwifi(O) mac80211(O) cfg80211(O) compat(O) ctr ccm arc4 autofs4 snd_hda_codec_hdmi snd_hda_codec_idt joydev coretemp kvm_intel kvm aesni_intel ablk_helper cryptd lrw aes_i586 snd_hda_intel xts snd_hda_codec gf128mul snd_hwdep snd_pcm snd_seq_midi dell_wmi snd_rawmidi sparse_keymap snd_seq_midi_event snd_seq uvcvideo dell_laptop videobuf2_core dcdbas microcode videodev psmouse snd_timer videobuf2_vmalloc videobuf2_memops serio_raw snd_seq_device btusb i915 snd bluetooth lpc_ich drm_kms_helper soundcore snd_page_alloc drm i2c_algo_bit wmi parport_pc ppdev video binfmt_misc rpcsec_gss_krb5 nfsd mac_hid nfs_acl nfsv4 auth_rpcgss nfs fscache lockd sunrpc msdos lp parport sdhci_pci sdhci ahci libahci e1000e mmc_core ptp pps_core [last unloaded: compat] [40026.117640] CPU: 2 PID: 3827 Comm: bash Tainted: G W O 3.10.29-dev #1 [40026.120216] Hardware name: Dell Inc.
