Subject: [PATCH] brcmfmac: don't realloc wiphy during PCIe reset
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: a1f5aac1765afbeace9581afa27da34085f68e1d
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
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.
