May I kindly bring up this reported problem again? Is there anybody working on
this problem? Or did I miss the already existing fix?

A fix has been found. The patched code is available at
https://GitHub.com/lwfinger/rtw88.git. Patches are being prepared for
wireless-next. From there, they will propagate into the Linux distributions.

Did you ever submit the second half of that patch?
https://github.com/lwfinger/rtw88/commit/0eed97166d54cf6fa03e20735b9c208375b8c949
(modifications to rtw_fw_c2h_cmd_rx_irqsafe())

We're still seeing leaks here with kmemleak, although I'm using a
5.4.y kernel, so maybe don't have all the latest fixes yet.

NB: I *do* have this: https://git.kernel.org/linus/191f6b08bfef
as it made it to 5.4.y.

Brian,

I fixed the leaks, but forgot to submit the patch. My repo at 
https://github.com/lafingerrtw88.git has the fixes, and does have any leaks on 
my system. The patch just pushed has the same fixes.
