This patch avoid this case. Well, another remark from Kalle was that this patch does not apply to wireless-drivers-next/master branch. So I tried to apply this patch and it failed.

Please rebase this patch. I have re-based this patch to wireless-drivers-next/master branch and sent it with the subject "[PATCH v3] brcmfmac: avoid duplicated suspend/resume operation" in another mail.
