Subject: ACPI: EC: Register a platform device for ECDT EC
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fe9542b8b53cd72cd6304278052a3d7db3f6c824;p=thirdparty%2Fkernel%2Flinux.git

ACPI: EC: Register a platform device for ECDT EC

To facilitate converting the ACPI EC driver into a platform one,
modify acpi_bus_register_early_device(), used by acpi_ec_ecdt_start()
for creating a struct acpi_device to represent the "early" EC based
on the ECDT ACPI table, to carry out the default ACPI enumeration for
the given device which will cause a platform device to be registered
for it.

No intentional functional impact.
