[PATCH] soundwire: add back ACPI dependency

[PATCH] soundwire: add back ACPI dependency

[Arnd Bergmann]

Soundwire gained a warning for randconfig builds without
CONFIG_ACPI during the linux-5.3-rc cycle:

drivers/soundwire/slave.c:16:12: error: unused function 'sdw_slave_add' [-Werror,-Wunused-function]

Add the CONFIG_ACPI dependency at the top level now.

Did you run this yesterday or today. I have applied Srini's patches to
add DT support for Soundwire couple of days back so we should not see
this warning anymore

This is on the latest linux-next, which is dated 20190904. As Stephen is
not releasing any more linux-next kernels until later this month, I'm
missing anything that came in afterwards.

That is interesting as next-20190904 has the DT changes :) Can you share
the config you used to get this.

I have two instances of sdw_slave_add() in next-20190904:

drivers/soundwire/slave.c:              sdw_slave_add(bus, &id, acpi_fwnode_handle(adev));
drivers/soundwire/slave.c:              sdw_slave_add(bus, &id, of_fwnode_handle(node));

Thanks

Ok, I remember now: the warning I got was actually on mainline.
It's fixed in linux-next, but from all I can tell, 5.3-rc7 is still broken.
