Dear Pavel,

Thanks for testing. It was very kind from you.I'll add this to the Reviewed-tag
that you had already given to my patch.

However, I intend to rebase and resend this 1/2 and the 2/2 of this series, because
(as we already found) they logically follow another patch of mine that is still in the
queue ("staging: r8188eu: Remove _enter/_exit_critical_mutex()").

The patch above has already been reviewed by Greg and he found that it looks 
good, but he cannot apply it because it is not tested (for the reasons I've already
explained with a couple of messages)

Unfortunately, until "Remove _enter/_exit_critical_mutex()" is not tested, Greg 
won't apply it and the 2/2 of this series cannot be applied too.

Please, if you have time, do you mind to test also that? It would allow me to resend 
it with your "Tested-by" tag and Greg will surely apply it. No worries if you have no
time for doing this test, otherwise you may find it at:

https://lore.kernel.org/lkml/20210819221241.31987-1-fmdefrancesco@gmail.com/

Please, if you are interested, read the whole thread. You'll see that Greg would apply
it, only if tested.

Thanks very much for your help and kindness,

Fabio
