[PATCH] ASoC: avoid unused variable warning for rt5659_acpi_match

[Arnd Bergmann]

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 removes the ACPI_PTR() to avoid the warning.

This is a harmless regression against v4.4, found on ARM randconfig builds
