Why not use 'struct device' as the argument?
Because of calls to platform_get_resource inside the function.
+void ahci_platform_put_resources(struct ahci_host_priv *hpriv);
Can we have 'struct device' as the argument? Else it becomes
impossible to get 'struct device' from 'hpriv' if we need to call e.g.
pm_runtime_*() APIs.
The plan for is for this function to go away once we have a
devm version of of_clk_get, so if you need to put pm_runtime_calls
somewhere, please don't put them here. This sounds like something which
should go in enable / disable resources instead ?
