Normally __acpi_match_device and __acpi_device[_uevent]_modalias are only called through functions calling acpi_companion_match() so that if their are multiple devices sharing the ACPI firmware node only one matches / gets the acpi:ACPIHID modalias. Some DSDTs defines multiple i2c devices in a single apci_device and in the i2c-core-acpi code we want to instantiate separate devices for these, with all devices reporting / matching the acpi_devices's modalias. This commit exports __acpi_match_device and __acpi_device[_uevent]_modalias for use in the i2c-core-acpi code only, with a comment added that they should not be used in normal code.
