This patch looks like a bug fix and it should go to stable kernels as well. The problem is this patch is made on top of 2 previous clean up patches, so it can't go to stable as is.
I think, the less painful way is to move this patch on the first place in this series. On the other hand you can just resend this one separately.
Or, maybe, Greg knows some magic that will help here, we can wait him before you resend 20 patch series :)
If you will somehow resend, please, add following tag:
Fixes: 8cd574e6af54 ("staging: r8188eu: introduce new hal dir for RTL8188eu driver")
Thanks for you clean up work on this driver!
With regards, Pavel Skripkin
