Subject: [PATCH] soundwire: intel: fix another unused-function warning
Git-commit: 17e0da0b8979a53977f684813f5c9db817d170e2
Patch-mainline: v5.11-rc1
References: jsc#SLE-16518

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")
