This makes brcmfmac use the same wiphy after PCIe reset to help user space handle corner cases (e.g. firmware crash). Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

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

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