+Subject: [PATCH] brcmfmac: drop unused pm_block vif attribute
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This attribute was added 3 years ago by
+commit 3eacf866559c ("brcmfmac: introduce brcmf_cfg80211_vif structure")
+but it remains unused since then. It seems we can safely drop it.
