The ASoC Sound Card driver can be compile tested with !CONFIG_OF
making 'loongson_asoc_dt_ids' unused:

sound/soc/loongson/loongson_card.c:200:34: warning: unused variable
'loongson_asoc_dt_ids' [-Wunused-const-variable]
Hmm, why not guard the definition with #ifdef CONFIG_OF instead?

Source text is first and foremost for the human reader, not for the
compiler, and an ifdef clearly shows the condition when the definition
is not used.
Rather drop of_match_ptr so this can be used also on ACPI.

This is more reasonable.

Please ignore the the patch,i will resend a new one.


Thanks,
