The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it is not relevant here). This fixes compile warning (!CONFIG_OF on x86_64):
sound/soc/samsung/smdk_wm8994.c:139:34: warning: ‘samsung_wm8994_of_match’ defined but not used [-Wunused-const-variable=]
