Could you please queue this patch to wireless tree? Because RTL8852BE becomes
unusable for some users. I assigned this patch to you in patchwork, if you
don't think so and have other suggestions, please let me know. Thanks. 

The user has reported this patch works as expected [1], so add his tested-by:
Tested-by: Marcel Weißenbach <mweissenbach@ignaz.org>

Also, I think this should Cc stable, so
Cc: stable@vger.kernel.org
