commit c361c5a6c559d1e0a2717abe9162a71aa602954f upstream.
pm_clk_suspend()/pm_clk_resume() are defined as NULL pointers rather than
empty inline stubs without CONFIG_PM:
drivers/clk/mmp/clk-audio.c:402:16: error: called object type 'void *' is not a function or function pointer
pm_clk_suspend(dev);
drivers/clk/mmp/clk-audio.c:411:15: error: called object type 'void *' is not a function or function pointer
pm_clk_resume(dev);
I tried redefining the helper functions, but that caused additional
problems. This is the simple solution of replacing the __maybe_unused
trick with an #ifdef.
