Re: [PATCH 2/6] PCI: dwc: Change arguments of dw_pcie_prog_outbound_atu()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Nit: could the subject line be more specific than "change arguments"?
E.g., something about collecting dw_pcie_prog_outbound_atu() arguments
in a struct?  If you know that's the fundamental change, it's a lot
easier to read the commit log and the patch because you know the goal.
