ACPI: processor: Return an error if acpi_processor_get_info() fails in processor_add()

Browse source

[ Upstream commit fadf231f0a ]

Rafael observed [1] that returning 0 from processor_add() will result in
acpi_default_enumeration() being called which will attempt to create a
platform device, but that makes little sense when the processor is known
to be not available.  So just return the error code from acpi_processor_get_info()
instead.
