   4 Subject: [PATCH 3/3] brcmfmac: don't realloc wiphy during PCIe reset

   9 Providing a new wiphy on every PCIe reset was confusing and was causing
  10 configuration problems for some users (supplicant and authenticators).
  11 Sticking to the existing wiphy should make error recovery much simpler
  12 and more reliable.
