I'm planning to queue this for 4.20 as wcn3990 support won't work otherwise. But I wasn't able to test this so can someone help, please?
Hi Kalle, I tested this patch on WCN3990 and did basic STA mode sanity. I do not see any crash with this fix. Thanks, Rakesh Pillai.

I now tested this with firmware 10.2.4.70.9-2 on QC988X. I'll update the commit log accordingly.
