5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@xxxxxxxxx>
[ Upstream commit a4754182dc936b97ec7e9f6b08cdf7ed97ef9069 ]
Evidently I had only looked at all the ones in rx.c, and missed this.
Add bh-disable to this use of the rxq->lock as well.
Fixes: 25edc8f259c7 ("iwlwifi: pcie: properly implement NAPI")
