Subject: [PATCH 4.4 112/342] rtlwifi: rtl8723be: Fix module parameter initialization

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@...inger.net>

commit 7079604ddb83f428359feace3aeaf8a9f435be4a upstream.

This driver has a number of errors in the module initialization. These
include the following:

Parameter msi_support is stored in two places - one is removed.
Paramters sw_crypto and disable_watchdog were never stored in the final
locations, nor were they initialized properly.
