Thanks for the patch.
I believe this is already fixed by the following patch:
commit 4bfb934b0067b7f6a24470682c5f7254fd4d8282
Author: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx>

[media] smiapp: Make suspend and resume functions __maybe_unused
The smiapp_suspend() and smiapp_resume() functions will end up being unused
if CONFIG_PM is enabled but CONFIG_PM_SLEEP is disabled, causing a
compiler warning from both of the function definitions. Fix this by
marking the functions with __maybe_unused.
