Subject: [PATCH] mwifiex: ensure "disable auto DS" struct is initialized
Git-commit: 9557d9f2e62b0c929510e4dda32013aa62453558
Patch-mainline: v4.14-rc1
References: FATE#326294
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.
