[]= { > {"SMO8800"}, > {"SMO8810"}, > ... > {} > }; Following table already exists in dell-smo8800.c file: static const struct acpi_device_id smo8800_ids[] = { { "SMO8800", 0 }, { "SMO8801", 0 }, { "SMO8810", 0 }, { "SMO8811", 0 }, { "SMO8820", 0 }, { "SMO8821", 0 }, { "SMO8830", 0 }, { "SMO8831", 0 }, { "", 0 }, }; MODULE_DEVICE_TABLE(acpi, smo8800_ids); Can we reuse it? Maybe moving array smo8800_ids[] into some header file (which one?) and statically inline it? Or having it only in dell-smo8800.c file and exporting its symbol? Or is there better idea? For sure I do not want to copy paste this table into another module and maintaining two copies of this list. -- Pali Rohár pali.rohar@xxxxxxxxx
