Subject: [PATCH] brcmfmac: handle FWHALT mailbox indication
The firmware uses a mailbox to communicate to the host what is going
on. In the driver we validate the bit received. Various people seen
the following message:
brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012
Bit 4 is cause of this message, but this actually indicates the firmware
has halted. Handle this bit by giving a more meaningful error message.

The function brcmf_cfg80211_escan() was always called with a non-null
request parameter and null pointer for this_ssid parameter. Clean up
the function removing the dead code path.

so there is no reason to split in two function especially since the latter
does not do an awful lot.

From bd99a3013bdc00f8fc7534c657b39616792b4467 Mon Sep 17 00:00:00 2001
From: Arend Van Spriel <arend.vanspriel@broadcom.com>
Date: Wed, 8 Nov 2017 14:36:37 +0100
Subject: [PATCH] brcmfmac: move configuration of probe request IEs
The configuration of the IEs for probe requests was done in a P2P
related function, which is not very obvious. Moving it to
.scan callback function, ie. brcmf_cfg80211_scan().
