From 08f0d23d97dcb49ca7ba65a3fc714a5d28a91d0c Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Thu, 10 Dec 2015 15:47:11 +0200 Subject: iwlwifi: avoid d0i3 commands when no/init ucode is loaded d0i3 commands are not supported in the init image, so take a reference to ensure we don't enter d0i3 during init image, and additional checks to prevent d0i3 commands when no fw image is loaded. Add a few WARN_ON_ONCE to the d0i3 enter/exit commands to ensure we send d0i3 commands only when the normal ucode is loaded.
