Subject: [PATCH AUTOSEL 5.4 41/55] rtlwifi: Use pr_warn instead of WARN_ONCE
From: Dongliang Mu <mudongliangabcd@...il.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.
