I thought about that and did not do it because here we are remapping resources that are _not_ PCI bus resources (ie it is not PCI BARs we are remapping), keeping the devm_* prefix would be more consistent to the typical device drivers remapping functions pattern (ie a typical PCI host controller driver would mix devm_ and pcim_ calls which is a bit hard to parse), that was my rationale. I am not too fussed about that either way, I am happy to update it to pcim_* though, it is Bjorn/Arnd's decision.I would vote for pcim_*() variant.
Me too, for brevity.

2. If you may notice there is no separate pcim_*map*() stuff, they are dynamically adapting to the case.I do not understand what you mean here I would ask you to elaborate a bit more please so that I can do something about it.Oh, sorry, there are two examples currently, i.e. pci_enable_msi()/pci_enable_msix() and pci_request_region*() which has no "m" in the name, but are managed on release by pcim_release(). Some developers consider this as a bad idea, but so far no patch has been sent to introduce pcim_*() variants of those. So, regarding to your stuff, I would stick with "pcim" prefix.
Sounds good to me. Thanks. -- tejun
