pinctrl: imx: Switch to LATE_SYSTEM_SLEEP_PM_OPS() 2024-08-23T16:15:52+00:00 Fabio Estevam festevam@denx.de 2024-08-08T16:27:50+00:00 811e62c80a879d717f7bd4a293eb2c66ed4560ba Replace SET_LATE_SYSTEM_SLEEP_PM_OPS() with its modern LATE_SYSTEM_SLEEP_PM_OPS() alternative. The combined usage of pm_sleep_ptr() and LATE_SYSTEM_SLEEP_PM_OPS() allows the compiler to evaluate if the runtime suspend/resume() functions are used at build time or are simply dead code. This allows removing the __maybe_unused notation from the runtime suspend/resume() functions.
