Firstly, thanks for the kind words, Dan.

It's kinda annoying how things have changed since the old days.
Apparently if someone now attempts to improve the low-hanging fruit, it gets
instantly accused of doing something awful...

Anyway, meanwhile I actually discovered some better versions of out-of-tree
drivers for rtl8732bs based on existing rtw888 driver [1], [2], therefore I
have no motivation left to fix up my "own brain slop".

And on more thing - whats the proper way to use get_maintainers.pl script
with `git send-email` when sending patch series? Apparently I used it wrongly
and managed to agitate lots of people in the process..
