If I change this API to return a a (const void*), the device_get_match_data() function need to return a (const void *). While implementing the ACPI piece, I have to convert an unsigned long to (const void *) in ACPI code so that the APIs are compatible. > > Lothar Waßmann > -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
