-Subject: [PATCH 2/3] brcmfmac: split brcmf_attach() and brcmf_detach()
- functions
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Move code allocating/freeing wiphy out of above functions. This will
-allow reinitializing the driver (e.g. on some error) without allocating
-a new wiphy.
