ArchlinuxのBroadcom 43142：インターフェースなし

BCM43142用のドライバが私のラップトップにインストールされているようです。

lspci -k
02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
        Subsystem: Dell Wireless 1704 802.11n + BT 4.0
        Kernel driver in use: bcma-pci-bridge
        kernel modules: bcma

ただし、デバイスに接続されているワイヤレスインターフェイスがないようです。

ip link

無線機器に関する情報は出力されません。 Archlinuxのドキュメントを確認しましたが、インターフェイス（wlan0など）をワイヤレスデバイスに接続する方法は説明されていません。この問題をどのように解決できるかご存知ですか？

dmesg| grep bcma

修正するdmesg：次のような結果が表示されます。
