Subject: [PATCH AUTOSEL 4.19 28/38] rtlwifi: Use pr_warn instead of WARN_ONCE
Date: Mon, 30 May 2022 09:49:14 -0400 [thread overview]
Message-ID: <20220530134924.1936816-28-sashal@kernel.org> (raw)
In-Reply-To: <20220530134924.1936816-1-sashal@kernel.org>
From: Dongliang Mu <mudongliangabcd@gmail.com>
[ Upstream commit ad732da434a2936128769216eddaece3b1af4588 ]
This memory allocation failure can be triggered by fault injection or
high pressure testing, resulting a WARN.
Fix this by replacing WARN with pr_warn.
