Will lead to things getting missed should they be added below this point. Prefer: sys_pwr = of_property_read_bool(tps->dev->of_node, "system-power-controller"); if (sys_pwr) { if (pm_power_off) { dev_warn(tps->dev, "system-power-controller requested but pm_power_off function already registered\n"); } else { tps65219_i2c_client = client; pm_power_off = &tps65219_pm_power_off; } } tps65219_i2c_client = client; return 0; } Or even better, just drop all this "system-power-controller" stuff until we figure out how we will handle it. The systems today using this PMIC will have PSCI being the pm_power_off controller, so we always go down the error/warn path here.
