Subject: [PATCH] brcmfmac: Fix for wrong disconnection event source information
Git-commit: 1b050d9711f9ce3657d00cca48d767d1ac622b6d
Patch-mainline: v5.9-rc1
References: jsc#SLE-13430

Current brcmf_link_down() always call cfg80211_disconnected() with
locally_generated=1, which is not always the case. Add event source
argument on link down handler and set locally_generated based on the
real trigger.
