Subject: [PATCH] rtlwifi: Use pr_warn instead of WARN_ONCE
Git-commit: ad732da434a2936128769216eddaece3b1af4588
Patch-mainline: v5.19-rc1
References: git-fixes
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.
