   4 Subject: [PATCH] brcmfmac: support repeated brcmf_fw_alloc_request() calls

   9 During a normal brcmfmac lifetime brcmf_fw_alloc_request() is called
  10 once only during the probe. It's safe to assume provided array is clear.

  12 Further brcmfmac improvements may require calling it multiple times
  13 though. This patch allows it by fixing invalid firmware paths like:
