Subject: [PATCH 0/3] brcmfmac: keep wiphy during PCIe driver lifetime

From: Rafał Miłecki <rafal@milecki.pl>

Driver's main init/attach function brcmf_attach() was handling both:
wiphy allocation and driver initialization. It meant getting a new wiphy
on every init (initial, resume, error recovery).

For supplicants/authenticators and Linux users it's move convenient to
have the same wiphy over driver's lifetime. It allows e.g. automatic
recovery after a firmware crash.

This patchset was tested on BCM4366 (PCIe) and BCM43430 (SDIO).

Right now only PCIe makes use of keeping the same wiphy. I got RPi Zero
W so I'm planning to add firmware crash recovery & keep wiphy for SDIO
in the future.

Rafał Miłecki (3):
  brcmfmac: move "cfg80211_ops" pointer to another struct
  brcmfmac: split brcmf_attach() and brcmf_detach() functions
  brcmfmac: don't realloc wiphy during PCIe reset
