Subject: rtlwifi: Use pr_warn instead of WARN_ONCE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7023fd8fabec9af83204e55e095695ff31aae0ed;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

rtlwifi: Use pr_warn instead of WARN_ONCE

[ 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.
