Subject: [PATCH v1 0/2] acpi: Remove acpi_release_memory()

Hi,

It seems there never were and there never will be actual devices that
expose the UCSI ACPI mailbox interface. There are now PD controllers
that support the UCSI interface, but they do not use the ACPI mailbox.

So there is no point in mapping the mailbox with ioremap(), we can
just use memremap(). That should make it possible to also remove the
function acpi_release_memory(). That function was only there to make
it possible to use ioremap() in the UCSI ACPI driver.

thanks,
