Without CONFIG_PM, there is another warning about an unused function:

drivers/soundwire/intel.c:530:12: error: 'intel_link_power_down' defined but not used [-Werror=unused-function]

After a previous fix, the driver already uses both an #ifdef and a __maybe_unused annotation but still gets it wrong. Remove the ifdef and instead use __maybe_unused consistently to avoid the problem for good.

Fixes: f046b2334083 ("soundwire: intel: fix intel_suspend/resume defined but not used warning") Fixes: ebf878eddbb4 ("soundwire: intel: add pm_runtime support") Signed-off-by: Arnd Bergmann arnd@arndb.de

Thanks for the patch Arnd, indeed that's a miss.
