Subject: [PATCH 08/14] mwifiex: ensure "disable auto DS" struct is initialized
Date: Wed, 24 May 2017 17:11:13 -0700	[thread overview]
Message-ID: <20170525001119.64791-8-briannorris@chromium.org> (raw)
In-Reply-To: <20170525001119.64791-1-briannorris@chromium.org>

The .idle_time field *should* be unused, but technically, we're allowing
unitialized stack garbage to pass all the way through to the firmware
host command. Let's zero it out instead.
