I thought that adding _add in just one case would be sort of odd, but of course I can do that, so please let me know what you want me to do. Cheers!

So why not rename those instead: platform_notify() to platform_notify_add() and so on? You are in any case modifying acpi_device_notify() in this series, and I think there is only one place left where .platform_notify is assigned. I believe you also wouldn't then need to worry about the function name collision (3/6). > I thought that adding _add in just one case would be sort of odd, but > of course I can do that, so please let me know what you want me to do. I would prefer the "_add" ending, but in any case, FWIW: Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com>
