+Subject: [PATCH] brcmfmac: avoid gcc-5.1 warning
+
+gcc-5.0 gained a new warning in the fwsignal portion of the brcmfmac
+driver:
+
+drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c: In function 'brcmf_fws_txs_process':
+drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c:1478:8: warning: 'skb' may be used uninitialized in this function [-Wmaybe-uninitialized]
+
+This is a false positive, and marking the brcmf_fws_hanger_poppkt function
+as 'static inline' makes the warning go away. I have checked the object
+file output and while a little code gets moved around, the size of
+the binary remains identical.
