From 8ca95995e64f5d270889badb3e449dca91106a2b Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Sun, 15 Sep 2013 11:37:17 +0300 Subject: [PATCH] iwlwifi: don't WARN on host commands sent when firmware is dead This triggers automatic bug reports and add no valuable information. Print a simple error instead and drop the host command.
