Subject: [PATCH AUTOSEL 4.19 38/59] iwlwifi: remove module loading failure message
Date: Mon, 17 Jan 2022 21:46:39 -0500	[thread overview]
Message-ID: <20220118024701.1952911-38-sashal@kernel.org> (raw)
In-Reply-To: <20220118024701.1952911-1-sashal@kernel.org>

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 6518f83ffa51131daaf439b66094f684da3fb0ae ]

When CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, iwlwifi crashes
when the opmode module cannot be loaded, due to completing
the completion before using drv->dev, which can then already
be freed.

Fix this by removing the (fairly useless) message. Moving the
completion later causes a deadlock instead, so that's not an
option.
