We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.

To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

Hi,

Found the problem, and this is my proposal for a fix.

Jérôme, please test it when you have time.

Hi Heikki,

I can confirm that this patch fixes the issue I've reported on the Lenovo
ThinkPad 8 tablet. You were fast to find the root cause, impressive, really
appreciated.

Feel free to add:

Let's hope it can still make it during the remaining 4.9 rc timing.

It's in my linux-next branch now (it should hit linux-next on Friday)
and I'm going to push it for -rc5 if it doesn't lead to problems.

Thanks,
Rafael
