I'm a bit worried about what you're trying to achieve from here ...

... to here.

Can you provide me with an explanation?

It's looks like you're trying to read/write to registers from /sysfs,
which frightens me a lot.

Put this at the top.  Also, if it's an ACPI ID, it should say so.

platform_get_irq()?

What's the point in storing a defined constant to a variable?

Just use the constant in it's place.

This is belt and braces.  The point of using ACPI_PTR() is so you
don't have to encase it in CONFIG_ACPI.
