Subject: Re: rtl8192cu: slow path warning

Hello Richard,

If you still have the required HW and still would like a patch to remove
that warning on your machine, could you please try the attached one ?

I slightly reworked the original patch by moving the function
rtl_lps_change_work_callback from pci.c to ps.c. 

I've successfully compiled that on my machine, but I have PCI set in
my .config, so I'd like your feedback.

Best,
Paul
