From ee942ecc42af9af0f0398861f636019f9726755b Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Mon, 12 May 2014 10:47:38 +0200 Subject: [PATCH] brcmfmac: handle 80MHz chanspecs in construct_reg_info() function The device is queried about the usability of channels, but it did not take 80MHz channels into consideration. This patch adds processing those chanspecs and clear the NO_80MHZ flag for those control/primary channels.
