Sure. I have one outstanding comment to be fixed on my legacy interrupt cleanup
patch in the MSI cleanup series. I'll resend the series without the legacy
interrupt cleanup patch so that we can get most of the patches for 5.1. I'll
come back to it later.

I'm not sure how many tested EPC features cleanup. However I've got ACK from
Shawn Lin for the v2 of EPC features cleanup series and Layerscape EP series
was created on top of EPC features cleanup series.

Thanks
Kishon
