[PATCH 12/12] iwlwifi: mvm: reduce WARN_ON() in TX status path

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

 



From: Johannes Berg <johannes.berg@xxxxxxxxx>

Evidently, it's possible to hit this issue, so reduce the
noise from it by just having it print a (rate-limited)
message instead. We don't really know yet why we hit it,
but there's no value in having a WARN_ON() here.
