Subject: [ 05/47] iwlwifi: update BT traffic load states correctly
Date: Thu, 07 Jun 2012 13:14:03 +0900 [thread overview]
Message-ID: <20120607041358.910470464@linuxfoundation.org> (raw)
In-Reply-To: <20120607041504.GA13819@kroah.com>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com>
commit 882dde8eb0d49ce0f853f8f4084dde56a21fe55f upstream.
When BT traffic load changes from its
previous state, a new LQ command needs to be
sent down to the firmware. This needs to
be done only once per change. The state
variable that keeps track of this change is
last_bt_traffic_load. However, it was not
being updated when the change had been
handled. Not updating this variable was
causing a flood of advanced BT config
commands to be sent to the firmware. Fix
this.
