   8 commit 22f44150aad7a1d6b074ab6cf59abee61c7187c6 upstream.
   9
  10 gcc-5.0 gained a new warning in the fwsignal portion of the brcmfmac
  11 driver:
  12
  13 drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c: In function 'brcmf_fws_txs_process':
  14 drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c:1478:8: warning: 'skb' may be used uninitialized in this function [-Wmaybe-uninitialized]
  15
  16 This is a false positive, and marking the brcmf_fws_hanger_poppkt function
  17 as 'static inline' makes the warning go away. I have checked the object
  18 file output and while a little code gets moved around, the size of
  19 the binary remains identical.
