The newly added rt5659 codec driver unconditionally defines an ACPI device match table but then uses ACPI_PTR() to remove the only reference to it, so we get a harmless build warning:
sound/soc/codecs/rt5659.c:4200:30: warning: 'rt5659_acpi_match' defined but not used [-Wunused-variable] static struct acpi_device_id rt5659_acpi_match[] = {
This changes both the OF match table and the ACPI match table to follow the same style, using ACPI_PTR/of_match_ptr to make the reference conditional, and using an #ifdef to hide the table. This also adds the missing MODULE_DEVICE_TABLE for the OF case and adapts the formatting to the same style.
Signed-off-by: Arnd Bergmann arnd@arndb.de --- I still want to give this some time in the random build testing to avoid introducing a stupid mistake, please apply after tomorrow unless you hear from me otherwise.
