From fc8a601e1175ae351f662506030f9939cb7fdbfe Mon Sep 17 00:00:00 2001 From: Alex Hung Date: Mon, 13 Jun 2016 19:44:00 +0800 Subject: [PATCH] hp-wmi: Fix wifi cannot be hard-unblocked Several users reported wifi cannot be unblocked as discussed in [1]. This patch removes the use of the 2009 flag by BIOS but uses the actual WMI function calls - it will be skipped if WMI reports unsupported.
