#1667312 — linux-next: build warning after merge of the wireless-drivers tree

Hi all,

After merging the wireless-drivers tree, today's linux-next build
(x86_64 allmodconfig) produced this warning:

drivers/net/wireless/broadcom/brcm80211/brcmfmac/usb.c: In function 'brcmf_usb_probe_phase2':
drivers/net/wireless/broadcom/brcm80211/brcmfmac/usb.c:1198:2: warning: 'devinfo' may be used uninitialized in this function [-Wmaybe-uninitialized]
  mutex_unlock(&devinfo->dev_init_lock);
  ^

Introduced by commit

  6d0507a777fb ("brcmfmac: add parameter to pass error code in firmware callback")

Cheers,
Stephen Rothwell

Thanks, for the report. I also noticed this, only after I had applied
the patch, but hopefully Arend sends a patch to fix this soon.
