From 331e789443618ca9cc3ed48ada4e670225cca036 Mon Sep 17 00:00:00 2001

Subject: [PATCH] brcmfmac: use provided channels for scheduled scan
User-space can provide list of channels in the schedule scan request.
This was ignored so all channels supported and allowed by the device
were used. This patch configures the device to use the channels as
listed in the request.
