[PATCH 5.15 113/667] rtlwifi: Use pr_warn instead of WARN_ONCE

From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 14:27:30 EST


From: Dongliang Mu <mudongliangabcd@xxxxxxxxx>

[ 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.
