From de2a3027f6f15e2f6558dc4d178282ccc1f054db Mon Sep 17 00:00:00 2001 From: Arend Van Spriel Date: Tue, 20 Feb 2018 00:14:23 +0100 Subject: [PATCH] brcmfmac: remove brcmf_bus_started() from bus api No longer needed to call this in bus layer so make it static and call it in the last phase of brcmf_attach() instead.
