Hi Arend,

The patch 5b435de0d786: "net: wireless: add brcm80211 drivers" from
Oct 5, 2011, leads to the following warning:
drivers/net/wireless/brcm80211/brcmfmac/dhd_sdio.c:1699 brcmf_sdbrcm_readframes()
	 warn: is it ok to set 'rxseq' to -1?

  1697                          cnt = brcmf_sdbrcm_rxglom(bus, rxseq);
  1698                          brcmf_dbg(GLOM, "rxglom returned %d\n", cnt);
  1699                          rxseq += cnt - 1;
  1700                          rxleft = (rxleft > cnt) ? (rxleft - cnt) : 1;
  1701                          continue;

This isn't a warning, it's just one of the things I audit.
brcmf_sdbrcm_rxglom() can return 0 so it's weird that we do
"rxseq += 0 - 1;"  Was that intended?
