   4 Subject: [PATCH] brcmfmac: Remove firmware-loading code duplication
   5
   6 brcmf_fw_request_next_item and brcmf_fw_request_done both have identical
   7 code to complete the fw-request depending on the item-type.
   8
   9 This commit adds a new brcmf_fw_complete_request helper removing this code
  10 duplication.
