[PATCH] net: rtlwifi: Use pr_warn_once instead of WARN_ONCE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dongliang Mu <mudongliangabcd@xxxxxxxxx>

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_once.
