Sorry YueHaibing as I have said to other patch doing this, this slave.c
is acpi specific but Srini has already send DT support for this so it
doesn't become acpi only and this warn also goes away. We should get the
DT support soon

[PATCH v2 -next] soundwire: Fix -Wunused-function warning

2019-08-22 Thread YueHaibing
If CONFIG_ACPI is not set, gcc warning this:

drivers/soundwire/slave.c:16:12: warning:
 'sdw_slave_add' defined but not used [-Wunused-function]

Now all code in slave.c is only used on ACPI enabled,
so compiles it while CONFIG_ACPI is set.
