FYI, this upstream commit has unbalanced locking. I've submitted a
followup here:

[PATCH] mwifiex: fix unbalanced locking in mwifiex_process_country_ie()
https://lkml.kernel.org/linux-wireless/20200106224212.189763-1-briannorris@chromium.org/T/#u
https://patchwork.kernel.org/patch/11320227/

I'd recommend holding off until that gets landed somewhere. (Same for
the AUTOSEL patches sent to other kernel branches.)

Regards,
Brian
