kernel: idle: fix builds with PM but no system clock (19cb44ba) · Commits · Wenxi XU / zephyr

PM depends on SYS_CLOCK_EXISTS in Kconfig but several boards have Kconfig overrides that allow the dependency to be ignored, so CONFIG_PM=y even though CONFIG_SYS_CLOCK_EXISTS=n. Fix the code so that the true dependency is reflected in the generated code. Signed-off-by:
