From: Arnd Bergmann <arnd@xxxxxxxx> Compile-testing without CONFIG_OF shows that the of_match_ptr() macro was used incorrectly here: drivers/remoteproc/stm32_rproc.c:662:34: warning: unused variable 'stm32_rproc_match' [-Wunused-const-variable] As in almost every driver, the solution is simply to remove the use of this macro. The same thing happened with the deprecated SIMPLE_DEV_PM_OPS(), but the corresponding warning was already shut up with __maybe_unused annotations, so fix those as well by using the correct DEFINE_SIMPLE_DEV_PM_OPS() macros and removing the extraneous __maybe_unused modifiers. For completeness, also add a pm_ptr() to let the PM ops be eliminated completely when CONFIG_PM is turned off.
