   3 Subject: [PATCH] brcmfmac: avoid gcc-5.1 warning
   4
   5 gcc-5.0 gained a new warning in the fwsignal portion of the brcmfmac
   6 driver:
   7
   8 drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c: In function 'brcmf_fws_txs_process':
   9 drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c:1478:8: warning: 'skb' may be used uninitialized in this function [-Wmaybe-uninitialized]
  10
  11 This is a false positive, and marking the brcmf_fws_hanger_poppkt function
  12 as 'static inline' makes the warning go away. I have checked the object
  13 file output and while a little code gets moved around, the size of
  14 the binary remains identical.
